Tom,

I labelled all the wires on the harness we used, the only plug that is missing is for the electronic distributor connection ( I extended the tach wire to hook up to your coil, I have the plug here from another harness and if you PM me your mailing address I'll mail it to you.

Suggest you make a list of the wires we actually used - easy to find as they are not coiled up. The rest are for things like lock up convertor and speedo etc..

What needs to be stripped out of the stock harness are alternator, starter, and A/C compressor.

I can take some pictures of the modified GM ECM box and the GM to MS adapter board. There are like 8-10 parts to solder on.
