Im working out the kinks on my SD L98 swap i have the motor ready to go and primed up, now i just need to figure out the wiring..... i have a SD harness cleaned up and loomed my ONLY holdup on this entire thing is the c207 connector!!!

Currently i have an 89 TBI camaro and the 92 SD is going into it, i have figured out the VSS issue, just gonna run the feed from the tranny directly into the ecm since the t5 puts out 4000ppm which is what the 730 ecm requires so thats taken care of (someone correct me if thats wrong )

As far as the c207 goes i have pulled up both the 89 and the 90-92 on austinthirdgen.org....putting these two next to eachother nothing matches up i dont even know where to start!

here is the 92, this is what i need to end up with :

and here is the 89, my start point:

if someone can clear this up i would be eternally grateful, this swap is 2 years in the making ( long time i know but ive been having to juggle a family with my budget) to my knowledge everything is taken care of except for this one snag, being that this car is my DD i need to be able to take it down for 3 days tops and get it back on the road, ill be having 3 of my buddies helping me and we've all got atleast 3 swaps under our belts so while they R&R the motor i can handle the wiring, hopefully it goes off without a hitch....

TIA!!!!

 

I just did this swap (92 tbi to SD TPI) and it runs great.

I made a chart using the schematics from both cars, and also included wire colors. This is similar to the one on this site, but includes vats, ps pressure switch, and maybe one or two other extras.

Heres the chart:

This issue with it is the c207 is jumping from an 89 to a 92, its different if you look at the diagrams the 89 has half the amount of wires written down as the 92, my SD harness goes all the way to the ecm my issue now is the c207 I have both diagrams in front of me and the 92 lists multiple wires for "fuel injection systems" whereas the 89 does not. Its just confusing
