looking for the wiring diagrams and wire colour codes for a 92 firebird with 5.7 tpi

i have them for a 90 camaro and if you want you can buy the ones for your car. they get the entire year to you for about 15.00.
they are very long and if you are going to do some real electrical stuff - you need your own set. its about 35 pages long with color coding and everything.
they send them over the net so you can just download the pdf files from the original wiring chargs.

i have the full maunel but give me specifics on what you need and i will tell ya what to look for. pins etc ?

I have a auto shop friend that printed out the wiring diagram for my car now I need to do a spread sheet to put it into a simple format. Example pin 1 red with white pin 2 and so on. I have elected to go this direction as it is fairly costly to buy the harness for the conversion to the ls1

you might give a shout out to brad@larryselectricsite.com he does wireing harnesses cheep you could possible get the harness for 100-200 buck not for sure but i bought one for 350 with ecm and all new with gm color code and has heated o2 sensors and upgraded ecm for the 730 you might want to send him a tell . if i am wrong in posting this let me know. not sure if i could or not

OK I have now gone as far as I can with respect to the wiring info that i have found on this and I need to know about the ALDL dianostic plug. Do I need to replace it with one from the model year of the motor I am putting into the car or will the one in the car work. the car is a 92 firebird and the LS1 is out of a 2002.

Looks like Im a little late to this thread

Refer to this site for simple diagrams and pinouts

Hopefully you are not butchering your SD TPI harness, but are using a common V6 harness as a start since the parts reused are the same

Anyways, the ALDL must be correct for the PCM you are using, so you need a OBDII connector to run the LS1 PCM. Do a google search or LS1tech search on that's pinout

Most of the tpi harness is reconnected into the ls1 harness i have a feww points that are not connected as in the connector that connects next to the pcm under the dash. there is on that is connection that connects to the fuel safety from the tpi motor that has a dark brown wire on the return have not found when that goes yet other than it runs in under the drive side next to the fues block. some of the others not connected yet are for the a/c system and the vss, data line,and so on. if i had to guess i am about half done.

Only brown wire I know of in the C100 come from the alt to the gauge and ties into the fan relay

my mistake there are three wires on the plug first opne is grey next ie tan and the last is orange where do they go

Oil pressure sending unit

You only need the tan one connected. The rest are to power the fuel pump if the relay fails while driving and can be removed without consequence

OK now I will have to say where does it get connected (tan wire). This wire along with 6 others. I am not 100% sure of where they go.There is a dark green that I think is the temp sensor, a pink wire that went to the coil (thicker #10 ga) with a white wire possible this one is the tach, Pink with black is a ingector wire on the LS1 there is a left and right bank can I join both to the one orginal or do I need 2 feeds if I need 2 feeds can I use the pink wire.
NowI will have to say I can wire most things but auto wiring is new to me and when you do not understand what each wires funtion is it can seem rather difficult. So that said thank you to anyone with the answers much appreciated.

This should help

The injector fuses are ran thru the C207 connector. You can re-use the stockers in the fuse block or add your own

The pink coil wire is your main source of IGN for the entire harness
