as the topic states. still werkin on it, taking way to long to get this car back together...

not sure what im going to do about the heating controlls yet, but hopfully i figure somthing out.

i have to get the heater box out of another thirdgen, but i need to get one from a car with vaccume vent selection. not sure what year to be looking for but i have to find one without A/C.. should be fun

 

looks good so far! have u done the wiring yet??

 

heres a pic of the engine bay too, i want to get the car back on its wheels before I start wireing, just doing a pre-install first, get everything test fitted before paint and body work.

 

another pic of the dash, I think this style suits the cars body style better than the 2000 style. looks a little boxier and radio and heating controlls are more directed to the driver.

 

any problems you ran into while doing this ?

i am looking at doing on in the spring..

 

nuthing yet, but I will keep everyone up to date.

I just lined the dash up with the steering colum bracket, seems to be centered.
Ive read some posts about other installs ppl saying that the dash has a 2 inch gap on the one side, cant remember which side.
I havent found that particular problem myself, the dash seems to be lined up and with a little tweeking and new lower brackets for the dash to be mounted to the car should work out just fine.
I cut out the old dash mounting brackets because they were in the way.

the biggest obstical to overcome that I can see is the heater box, but there are posts about the 4th gen dash side being modified to fit the 3rd gen heater box assembly. wont know for sure till I find a parts car. Also Ill have to get a Dakota digital box for the speedo.

Im just going to follow the wireing cross reference in one of the sticky posts, I trust the guys that figured the wireing for the cluster and headlights got it all covered.

 

If your using a factory tbi car harness or sd tpi harness, hell even a maf harness, you shouldnt need an sgi5 for the speedometer.

 

im using a 88 TPI wiring harness.. where would the signal come from?

 

On an 88 camaro normally the speedometer gear drives the speedometer, then the back of the cluster the actual vss sends a 2000 pulse / mile signal to the computer to feed it, on a 90-92 tbi car the vss sends a 4000 pulse raw signal to the buffer box which outputs a 4000 pulse / mi for the instrument panel and 2000 for the ecm and cruise control.

Run a stock VSS and buffer box and your set.

On the other hand you may have some issues with the tach, another guy here who did the swap with his firebird dash says he's checked out the wiring etc and its still not working right, so far from what he's said and i've looked at, there is likely a filter in the stock 4th gen wiring inside the dash which is needed.

 

I was just looking at the wireing diagrams for the 88 wireing harness, you right vss signal from the cluster. wish I would have grabbed that cluster out of that car before I scraped it.

oh well I still have to get a parts car anyways for the heater box.

would it matter on the vss signal if the car has a V6 or V8 or tbi?

 

The easiest is the 90-92 V8 TBI, get the sender and buffer box.

I believe it should be the same in the 86-90 firebirds but dont quote me on that one.

 

i found this speedo with wireing coming out of the back, dont know what year it is, whould it work, or is there a way to test it?

 

shouldn't work, i've got the same setup on my 85 bird and it won't work for running the speedo. It's apparently sending out a different signal to the ECM than the speedo needs, 4000 PPM (speedo) to 2000 PPM (ECM). The unit is actually cable controlled, and it converts it to an electronic signal. What's needed, is an 86+ firebird speedo, or a 90+ camaro setup, these have an electric sender in the tailshaft of the tranny, and convertor box behind the dash. The convertor box sends part of the signal to the ECM @ 2000PPM, and sends 4000PPM to the speedo. Those were times i wished i had an 86, wow, would the swap have been simple.

 

looks very good man

 

if I get the speedo vss from a 91-92 camaro or the 86-newer firedird to run the new 94 camaro spedometer then how will my computer work with this different signal, the ecm is from a 88 camaro.

 

cant wait to see finished product

 

there's a buffer box which is used to convert the signal from 4000 ppm to 2000 ppm. What u do is wire from your VSS the 4000ppm signal, that signal goes into the buffer box, a 4000 ppm signal comes from the box and goes to the dash for the speedo. The converted signal also comes from the box, and goes to the computer and cruise functions. It's a little yellow box found behind the pass. side dash on birds, and probalby those late model maros. 86+ birds.

 

for your speedo... along with cruise and ecm to work.... you need too use the buffer box and hook it up as follows using a vss from a 91-92 camaro or from an 86?-92 firebird.....

vss purple to connector 1 pin c on box
vss yellow to connector 1 pin a on box

pink/black on box connector 2 pin h to gauges fuse (10a)
brown on box connector 2 pin f to ecm input a10 connector 1
brown on box connector 2 pin c to speedo
red on box connector 2 pin e to cruise
blk/white on box connector 2 pin a to ground

hope that makes sence....

that will get your speedo to work correct as well and your cruise and of course your ecm

 

thanx guys, very helpful..

Ill keep everyone up to date on the progress..

 

looks great, i'd like to know more about adapting different heater controls to our current setups for the heat myself. keep up the good work.

 

Looking good man, i cant wait to see finsish pics, keep me updated

 

looks good. i would fit the console with the carpet and padding though, my console moved almost and inch with the carpet and padding back in so the new panels didnt fit anymore.

honestly, i did the dash a year ago, it does make the car more comfortable to drive, but i dont like it at all. im thinking about going to a different dash, or a all out custom dash.

keep up the good work

 

Hey,

that looks awesome, what year camaro is that out of?

 

the dash is out of a 94 camaro

 

i went to the autowrecker today, i picked up the wireing for a 88 firebird with a 2.8 FI

can anyone tell me if these boxes are the buffer boxes im looking for to run the speedo

this is the pic

 

The bright yellow box is the VSS buffer.

 

thanx...at least i got the right thing LOL...any ideas on what the inputs and outputs are on it?
