anyone with an 86 Trans am with TPI on here that can send me as many pics of their harness as they can? i think my harness is a speed density type, but im not sure if im missing some components, if anyone has a labeled diagram of a harness or a labeled picture of a harness that would help imensely

 

not that clear but i think it'll get you by. http://chevythunder.com/fuel%20injec....%20pg%20C.htm

 

i need to buy a wiring harness for my 86.. anybody know were i can get one cheap?

 

Ive never seen one in the internet. Call GM. I do believe that there are some in Summit or Jeggs. If memory serves me right, I think it was listed as around $400. It's a bit pricey but it's worth it.

 

where are you located? i know a guy that always has harnesses

 

You think you could get me a harness for 91 tpi i am located in CA though

 

where in CA. I live in the Imperial Valley.

 

Im all the way in IL, i can call my guy, he asks bout 100 for a harness though, but he usually gives all the relays with it

 

IL. thats far. What about JR350tpi , where are you at in CA?

 

Yea i live in California by Los Angeles

 

I was born in Huntington Park but just after birth my parents moved back south so I dont remember anything. In 2005 I lived in Rialto but then moved to Hemet. I worked all over the Inland Impire and as far North as Rosemond. But the housing market crashed and the company I worked for began to lose work and ineviably I was laid off. Sucks. What city u from?

 

86 was MAF ; not SD.
If your harness is for SD TPI, it will have this connector for MAP sensor http://www.tpiparts.net/inc/sdetail/2343
coming out of engine harness that connects to the injectors on pass side The MAP sensor is directly above # 6 & 8 injectors.

A MAF harness has this connector http://tpiparts.net/inc/sdetail/816
on the pass side engine harness right out the front , pass the connectors that plug into the TB (TPS /IAC ) sensors.

 

I live in Norwalk and have been living here my whole life

 

Coo, Coo. In 05, I had to go to Norwalk to get my birth certificate because i had lost my original one. Let me tell ya, I stood in line for 4 1/2 hours just to be seen for 2 minutes and pay I think it was $15. Well good to meet you JR350TPI. Peace.

 

Does the harness he sells complete if he does check if he has one for 91 i need it for a swap i wanna do

 

I seen that you are gonna do a 350 swap too is it going to be a tpi or carb cause i am gonna do that swap too in my car thats why i am looking for the things i need.

 

Sup bro. yup, I already have the 350 block in the Camaro. All I got to do is finish routing the vacuum hoses and set the timing. I cant do it in one day because Im married and have 3 kids. I work graveyard and my wife works in the evenings. My Camaro is at my grandmas house where my 45 year old uncle still lives. Hahahahah. He is 45, and his last girlfriend he had was in High School. So he pretty has no life other than side side jobs as a mechanic. Im using the same setup. TPI. Everything bolts up correctly. See, whether your block is a 305 or 350, TBI or TPI, the block itself is all the same. The only differences are that the 305 cylinder walls measure under Approx 4 inches where as the 350 block is pretty much 4inches. You cant bore out much from a 305 block because the cylinder walls are not as thick as the 350. If you have a 305 in the Camaro and want to take it out to replace for a 350, I suggest use the 305 heads with the 350 block because the 305 heads have the big valves. Also the 305 heads will have more material in the combustion chamber and that means more compression. People will tell you not to do it but when I ordered my master overhaul kit and pistons, Summit racing told me to either use 305 heads or 327 heads. But the cool thing about Chevy blocks in our f-bodies is that whether its a 305 or a 350, everything bolts right up. The obious difference is the intake setup. Keep in mind that some blocks that are the the same (casting number wise), can be 2 bolt main or 4 bolt main. Another difference is the valve train. Some blocks have roller lifters and others have the tappets (solid lifters). If you go and buy a block from some one, take a 1/2 inch socket set and try to turn the crank at the crack shaft bolt to verify if the block is siezed. If the crank spins rather smoothly ( with the spark plugs removed) then chances are that youve got a good block. I found my block at a privatly owned junkyard. It had been sitting in the bed of a truck for about 4 years uncovered. I had it dipped in acid, power washed and magnafluxed. I had to retapp all the bolt holes to remove sand and rust. Now Im almost ready to fire it up. well i think we are in the wrong thread to be talking about this. P.M. me if you have anymore questions. I will be more than happy to help you out man. Peace.

 

I already have the engine i bought it about a month ago and i already rebuild it too only that my tpi harness it has is from a 87 and it is not complete so i need to convert the one from my car for it could go with the tpi, would you happen to know anything of the wiring for you could help me this is my first engine swap so i am just learning.
Sorry Chevy8588 for putting this in your thread

 

why can you no use your current harness?

 

I could but i have to convert it for it could have the rest of the conncetions for the TPI but they charge $250 for that, and i am in a really tight budget right now

 

Sorry bro. You would have to get a wiring diagram which tells you the color of the wire to so that you can match em. On the Haynes manual it gives you the wiring diagrams but of course you would have to dish out around $20. I guess the only big problem that you would have is the connections itself. for example, For my 86 IROC Z, it has a 4 prong connector as for the 87 IROC Z, it has a smaller 4 prong connector and another that remotes to a seperate coil. It really gets complicated bro. you would have to have your Camaro next to another IROC-Z model to use as a reference if you choose the wire up yourself. If you have the time, assoon as I get my 86 completed, I can send you pictures of the connectors so that you can get an idea of what you need. But then agian, I think you have have to visit the junkyard to get a ECM that belongs to an IROC-Z because the prom is already programed for the sensors that are involved in the Tuned Port Injection System. It'll be a challenge bro, but if you are determined and have time, and with a little extra money spent here and there, you'll get it going. Let me know whats on your mind. Peace.

 

understood, ill give him a call and see if he has anything for yah, we could work something out im sure

 

So i would have to get a ECM from an iroc but they have tell that i need to get a 90-92 tpi ecm and also a 90-92 tpi wiring harness for it could go on my 91RS, also that i need to get a custom prom and in total i found out it would be $700 from the guys who would do it for me.

 

If you could get me one that s complete that would be awsome because i have seen them for sale but they are not complete and also i dont know how to do all the wiring work.

 

what year harness do you need? HEI distributor or remote coil? and Speed density or MAF?

 

Yup. To burn a PROM costs serious money. But if you look in junkyards or on ebay perhaps, you can find a ECM for the year that you need. for only around $100. The DYNO shops will say anything just to make a quick buck. I will garantee you to that they will never say "look in a junkyard."

 

I need a 91 tpi and Speed Density, also with HEI, thank you if he also has the ecm tell me

 

you will have a slight issue with that, yer going to have vats in 91

 

what is that is it a big problem or what

 

VATS - Vehicle anti-theft system, measures the resistance in the pellet in your key. you have a 1 in 15 chance that your key pellet will match. wrong resistance = no start

 

So their is no way i could take that off the VATS or should i just stay with my tbi system

 

hmm as i recall there is a way to re-pin your TBI system to SD TPI, since TPI is batch fireing. its a sticky on the TPI forum. i do not know if that will utilize yourcurrent ECM or not though. BUt that will at least give you your TPI harness. as for the ECm you would either need to have the VATS edited out of your prom, or find a PCM thet they know the vats resistance, otherwise you can get some resistors and make each of the 15 values till you find the one you need and bypass the system.
