My company has an account with Newark, so I ordered from them.
All the variations and part numbers and such are still a real bear...even after doing it once. There is a chart that shows the different connector body sizes (shell size) and there are different numbers of pins and layouts in each size.
The pins and sockets are all common, and available in either 16-18 gauge or 20-24.
Each engine and ECM will of course vary some but I ended up with:
IAC = 4 wires
TPS = 3 wires
Inlet air temp = 2 wires
Injectors = 5 wires
Distributor = 4 wires
Coolant temp = 2 wires
Fuel Pressure gauge = 3 wires
That looks like it totals to 23.
So the one I got is perfect, cause the max number of wires in the next smaller shell size is 23, and then I wouldn't have any room "for future expansion...lol."
I'll get a pic up of the completed harness tomorrow. It's looking pretty trick. I got this woven nylon cable covering from cableorganizer.com in a few different sizes, sealed the ends with heat shrink. Harness looks very trick and professional. And when the air cleaner is on, ALL the wires disappear! You'd swear it was a carbed car.
(Injection is Holley 4bbl TBI)
