hey, I wanna know what's involved...please tell me

Ok,for it to run you have to move the ignition control#2 wire for pin 17 to 18. To do tha you have to drill that pin hole out in the 60way connector. Use an 1/8" bit but be super careful(maybe clamp a visegrip on the bit and twist it by hand) cause if you go to far you can ruin the retaining clip. I know this from experience after converting a 91 8valve Daytona harness to TIII

I only drove it up and down my road a few times(2.5" straightpipe and its midnight)and it seemed to run like like it did with the stock one. But I will do some more testing when I get a little more time. I know the cruisecontrol wires have to be switched and I can tell you where they need to go if you want. But the only thing is my OTC4000 was giving me some weird readings when I was data-logging it with the 91 SBEC. It went back to normal when I put the 93 back in so I know that its not perfected yet. I have a feeling we can get this to work in the long run if I can get some help from some of you. I just wish I had a whole day I could waist doing stuff like this

[turbo_III]

gladly, i'll help in anyway I can although I don't have a 91' SBEC to play with...


oooooh this is getting exciting!!!!

also good news, I have '91 and 92' wiring diagrams now

good old mitchell on demand:)

I do believe I have a 91 that was supposed to be a 92. Let me know if you need it for testing or anything Jackson.

oooh, going to the wrecker this weekend to pick up some harness' and a computer, gonna see if my idea will work, i'll keep you posted

[turbo_III]

i'm gonna have a '91 SBEC in my hands this weekend hopefully(or later next week) to do some testing!!

i'll go look for the diagrams real quick...

91 R/T





















92 r/t coming in just a sec...

[iniviate]

This is the 92 R/T Stuff...

[iniviate]

actually... i might be able to get diagrams for anything else too. i need to see if i can still log in to my former source. :)

[turbo_III]

well thanks alot for the diagrams, although I already found some of my own but im sure it will be useful for others...i've got everything ready to roll on my end just working on the cruise circuit right now..then i'm off on saturday to pick up a '91 R/T computer so I can put the wiring to the test

awesome...I"m greatful for how well this thread brought people's attention to this matter...as I know Jackson helped me out alot.

Here's exactly what is involved to get your car to run and extras so far as I've scanned the diagrams for two days now....

As Jackson posted, move pin 17 to pin 18..

Pin 57 needs to move to Pin 8 for the ASD Relay

And for the cruise to work(this will be the most time consuming)...

Pin 23 needs to move to pin 50

Now you need to run a few wires from the Clock Spring(in the steering column...Jackson might be able to shed some more light on this)

Pin 48 goes to the WHT/RED wire on the Clock Spring

Pin 49 goes to the Pin that doesn't currently have a wire(this is if the clock springs are the same in the ''92/93's as the 91's

As far as i can see everything else should work... if anything is incorrect here please post so we can all know

On another note,everything seems to be the same from 91 AA body(Spirit) and the 91 AG body(Daytona)dash and body control module. I know this for a fact cause my 91 Daytona ran perfectly with a 91 TIII SBEC. The only things we have to look for is what they changed or added in 92 that the SBEC controls in the car.

Everything that is inside the car is controlled by the BCM is it not?

MAking the car run is pretty easy. Making the tach and cruise work, well, that's a bit more involved. Once on 91 TIII electronics, the TrimCal will work for you.
