Erins car just has one orange wire to the ALDL which is on the upper row

 

Would it be easier if I put the wiring schematics and pin-outs of the ECM, C100 connector, and C207 connectors for the 89 into a pdf format and e-mail them to you tomorrow along with some other information. Might save a little on this posting back and forth.

 

Accually I have it all fro mwhat you said but those 2 wires are the last ones. Her 5v Grey referance comes out her dash and then ends. Its suppose to be Pin D but Pin D is the 89 Coolant and pin M on the 89 side is a B/W wire but there no B/W wire on the 91 pin m side. Those are the last two I am having troubnle with

 

Okay, I just went out to my car and checked the wiring on it and also went back over the schematics. The gray wire for the TPS does not go through connector C207 on an 89 car, it is a straight shot from the TPS to the ECM through the wire bundle behind the right kick panel. Pin "d " of the C207 for the 89 is a brown wire coming off the FP-FAN fuse on the fuse panel and goes to the coolant fan relay. On her car, that brown wire goes to pin "G8" of the C100 bulkhead connector to the coolant fan relay and probably needs to be re-routed. I hope this makes sense and helps you out.

 

Okay,

On a back-up and re-group from my last post in the event that you had already read it. Pin "M" of the C207 connector on the 89 cars is a ground wire and on her car, that wire goes to pin "C7" of the C100 bulkhead connector and should be re-routed to C207. The black/white wire from the MAF is a straight shot to pin "D1" of the ECM.

 

listen to this. We got most under control encept the injectors wont fire. THEN I go to jump the aldl and the light blinks so thats good then erins like um whats that ticking. I'm like WTF the injectors are ticking without starting sO i hurry up and turn it over and vroom it fires up. WTF didnt I wire in right? It starts with the aldl jumped but thats the only way. B/W W/B wires do it

 

We grounded Pin M on the 89 harness and the car fires right up. Only problem now is that we cant get it to charge. We ran the tan/white wire from the coolant fans and alt right to the fan fuse wire with no dice. No fans ether. Other then that so far so good. Surges at idle though pretty bad. Its only showing 9V on the guage. I figure once its 14ish it'll smooth out some I hope

 

Should G8 have power at it with ign on? We ran pin F on alt and combined it with the relays from the fans and wired it righ tto G8 with noooooooo results. Nothing changed.

 

Maybe these two schematics will help you with that. Please note the lines marked with an "X".

Trickster, that looks like the way the 89 is wired. On the 92 Camaro, cavity G8 in connector C100 does go to the 20 amp fan fuse and is tied into alternator terminal f. This circuit has power with the ignition on.

In the earlier TPI harnesses, that circuit went through the I/P harness, in the later TPI harnesses, that circuit only went through C100.

 

You are correct there S10Wildside, that is why they are having so many problems here. They are using a 89 engine harness and a 91 dash harness to make this thing work with an 89 ECM. This was explained in one of my posts earlier. This schematic is out of a 89 camaro.

 

If the 92 fuse block and C100 (the section in the car), is being used, then the circuit that goes to the fan relay(s) and alternator terminal f should go to G8. If you connect that circuit to C207 (I/P harness) from the 92 car, it won't lead to the fuse block.

I think they need the diagrams for the 92 Camaro. Maybe I'm reading the question wrong?

 

You are.

 

I followed Pin F on the alt and the 2 tan /white wires and they lead to the 207 connectors. The Fan use on the c100 for the 91 lead into the bulkhead. I directly connected G8 on the c100 on the 91 with The tan/white wire on the 89 c207 terminal. Is this what I am suppose to do? I'm sorry for being so dumb when it comes to this but I'm having a hard time reading this

 

See if this one helps.

 

Thats exactly what I have. but no dice. No fans. I have fans if I take of fthe relay and jump it using a wire they will turn on, but doing it other ways noway. When I jump the aldl the SES lights flash and the injectors tick lol I replaced all relays too. Should i have power to the fan fuse? I put a test light to the fan fuse both ends and no dice.

 

When you checked power to the fan fuse did you do it with the key in the "ON" position. Also, on the 91 fuse block the orange wire from the ignition switch goes to the HTR/AC fuse which is linked to the fan fuse in the fuse block. On the 89 it goes to the FP-FAN fuse with a seperate orange wire going to the HTR fuse. Your injectors firing when you jumper the ALDL is screwy because the wire for the driver side bank is a pink wire going from the INJ 1 fuse to pin "B" of connector C207 and the passenger side bank is a pink/black wire going from the INJ 2 fuse to pin "G" of connector C207 and from there they are a black wire going to pin "A" of each injector. Pin "B" of each driver side (INJ 1) injector is a black/pink wire going to pin "D15" of the ECM. Pin "B" of the passenger side (inj 2) is a black/light green wire going to pin "D16" of the ECM. Check the wiring on your fuse panel.

 

Key was on and NO power was getting to the fan fuse.

 

Drop the fuse panel down and see if there is a orange wire going to the FAN fuse. If not, there should be for it to work.

 

I have not looked since I am at work but I am pretty sure there is NO orange wire. If not where would this orange wire come from? Can I run a direct wire from the batt through an inline fuse then attach the T/W wire to that if there is none?

 

All is good and we took it on its maiden voyage. ONLY problem we found was that the MPH is not working. Oil, tach, water, gas, and volts are all on the money. MPH just wont work. VSS is plugged in. Am I missing something?

fans kick on The connection was bad.

 

Yes, the VSS on the 91 has about five connections for the ECM and the 89 only has 1. The pin connections used for the 91 VSS are either already in use on the 89 computer or not compatable (not functional slots). That's good about the fans.

 

So I'm kinda SOL on the MPH then?

 

On another post I found while searching for "c207" a guy said he put an 89 in his 91 and had to add VSS wires to D4 and E4 whatever that means.

 

I don't know, but on the 89 ECM pin "D4" is used by the spark timing input and there is no pin "E4". On the 91 ECM. pin "D4" is not used and pin "E4" is used by the Idle Air control"A Lo".

 

Here is the link that you were talking about. He added the VSS wires to pin "D4" & "E4" of the C100 connector on the firewall.

Here is another link for you. Do a search of the board under VSS and you will 2170 posts regarding it. Unfortunately, he does not say where he ran them to.

 

Okay, went back through the books and the posts on the VSS and here is what I have found. To make the VSS work on your car you will need to get a VSS buffer box and mount it in your car near the ECM and wire it according to this schematic. The signal wire will go to pin "A10" on the 89 ECM which is the same location on both computers. The yellow wire from the VSS on the tranny will go to pin "D4" of connector C100 and the purple wire will go to pin "E4". Wire it up in this fashion and you should have no problems.
