Need help with 993 ECU wiring to retrofit EFI
 

All, I'm installing an aftermarket EFI system on my 95 993. I'm in need of someone who can provide help identifying the purpose of the various wires on the chassis side of the two 14 pin plugs found under the drivers seat.

I've bought a subscription to alldata but I'm lost following the traces, and I can't determine the what's going on with the complexity of the DME relay.

I'd also like to eliminate the interruption circuits from the airbag computer and the remote door lock/alarm unit. Too much to ask for?

I've only been able to identify tach, power, switched power, inj 12v+, and one random leg off the DME relay.

Anybody able to give me a hand?
