HI, I am working on my conversion for a 1993 mazda rx7 and I have a lot of extra clips on the wire harness near the two large clips for the PCM.
Is there wire diagrams for the ls1 engine somewhere? I have the pins for the two large connectors...
Thanks

I have pinouts on my web page in the sig. I have the pinouts for the connectors that connect the PCM harness to the body and underhood harness.

Thanks, that is a huge help! Where did you get those pin outs from? is there some sort of shop manual for the ls1?

My own disassembly of the harness, diagrams, and help from this forum.

get yourself the shop manuals for the donor car at helminc.com.

THanks for the link!
will the service manual for $120 have the info I need, or do I need the $300 CD set???

There should be 3 connectors near the 2 pcm
80-pin connectors, 2 10-pins and one 8 pin, these connectors connect to the underhood wiring harness which contains the fuse boxes.

Factory manuals come in 3 volumes(books) sets.

vol 1-HVAC/power steering/suspension/brakes/abs
this volume isn't needed

vol 2-eng mechanical/eng electrical/eng controls
wiring diagrams of all the eng related stuff also has connector end views and component locator(drawings of where all the connectors are) all the engine dtc's, and also explains how all the engine controls operate. engine mech is cool it has exploded views of the engine, all the dimensions and all the tread pitch and diameters of all the bolt holes

vol 3-trans mech and elec/all other electronics
all electrical circuits in the car, power and ground distribution, also how the fuse boxes are wired, connector end views of alot of connectors

not only do the manuals have enough info, you dont have to print it all out or stare at a computer screen,
