Well, I got some more done in the last couple days, this is the clean stuff, just wiring, soldering, heat shrinking, electrical taping and fitting. Kinda fun, and once you know where everything goes on the harness, wiring becomes much less scary!
Here's what's left of a '90 harness for the engine bay side.
Not much here either, except the other end looks like a rats nest still. Mitsu couldn't put the wires in some kind of order, could they? Noooo.. but it's ok.
Yarr! Thar she blows! Well, that's it with the wires through the firewall. Amazing that it had the length.
passenger and exhaust side: coil pack, transistor and noise filter, o2 sensor, knock sensor, and that's about it.
Good thing my harness only has long length, and not girth, otherwise it wouldn't have fit through that hole.
Passenger footwell. Enough length to put the new ecu where the stock one was and try to hid all the naughty bits (as my former boss used to say).
Next I'll be working on splicing wires for fuel pump, tach, power, switched power, etc. there's probably a good 10 wires to finish up then I can plug'n'play just like if I had an eclipse or something not as cool as a conquest.
