I saw TurboSBC or whatever his name is had info on one, I PM'd him but never got a reply so maybe he'll chime in on it.

[Scottydoggs]

i tried to pm him, his box is full........so its post time.

[Booba5185]

Bill will probably chime in, he sold some back in November.

I've got one another member built for me. if nothing else i can snap a pic and send it to ya if that would help you

[Scottydoggs]

id need to see the pin #'s on the pcm plug. to sse that the black plastic cover needs to be taken off.

[Booba5185]

I can try and get those for ya Scotty, lemme fire up Alldata...

[Scottydoggs]

i need the serial data (uart) pin # it looks to be on the next plug.

[Scottydoggs]

i found a post with the pin outs. im only seeing pin 15 as a serial data, im not seeing the other one on the same plug.

[Booba5185]

Alldata was a no go, just schematics. I found these pics in another thread though:

Damn it. you found it the same time I did, lol.

[Booba5185]

C2 pins 2 &3?

[Scottydoggs]

thats the one, but i know for a fact people have made them with only the one plug.

[Booba5185]

It's gotta be that pin 15 then, you don't have a PCM laying around do you?

[Scottydoggs]

thats the thing, i dont have a 04 pcm. 15 gets used, then you need the other two pins as well. as per a 07-03 off board, aka going for the same wires.

[Booba5185]

Hmpf. I wish someone that has built one would chime in. I know the ones Bill sold were 2 plugs. You talking about that one TurboSBC made with the metal plate and diodes?

[Scottydoggs]

i just need to know what pins to use off the one plug lol im not using diodes and crap. all i know is its been done with one plug.

[Booba5185]

I know, you know what I mean though.

Pin 15 on C1. Give that same connector power to the IGN wires and then use one of the low references as a ground. Otherwise use the mother of all grounds on C2.

[Scottydoggs]

ive got pin 8 for ground, 15 for class data, 18 and 19 for ignition power.

if i power 15 wheres the data gonna cross over from?

[BillBoost37]

Christ.. youre effing killin me.

Data pin 15
Power anything labeled ign
ground.. any of the lows
