I recently just bought my dream car for dirt cheap but with this dirt cheep come the weekend tinker and airgun happy tight. So the wire nut lights got ripped out along with the radio. I have no mem voltage at the connector. My interior lights don't work,reverse lights, dash lights for wiper control and headlight switch,the wiper fluid motors, the 4 way flashers, The a/c , magnet clutch. I am pretty sure that' is it. I have traced battery power to the E6 point in the fuse box Tested all the relays by the 60-80 ohms on the coil side and gave each relay a 10 amp fused jumper the test the switch side ( that's all relays in the car). :crazy: The the fuses next the the drivers foot all have power to the when they are supposed too. About the only thing i have come up with that they all have in common is Connector E102 to M7 and i have no idea witch on that is or even that might be it. So please if you have some input Pretty pretty please HELP. :ohno:

Oh well ill respond to my own question (in some weird three person split personality thing). Well if you take out both the engine room harness and the Main wire harness [( i know a s*** ton of work)But the Z is worth it] You will find that at connector E102/M7, Some jack wagon, actual took apart the connector and put it back together wrong.(what a wrinkled dirty hole) Also while inspecting the rest of the harness you will probably find the most amazing electronic wiring ever, where most of the wire brakes, from overloading, are wire nutted together and where he just got lazy (or out of wire nuts) left it cut. After 3-4 hours of soldering and putting it all back together you might have a working car.Oh yes and here is the pin out of the time control unit cause your set daughter might just close the door in the wiring harness again. and its looking at the back of the female side of the connector

oh yes and my wife was quite pissed at me. the only problem left is an intermittent on/off of the digital climate control. Itll come on sometime when the car starts but go off when i turn the lights on.All the lights will work. but than sometimes when i turn the lights on it will go off. I might of missed a few splices being the amount of cuts in the harness and the amount of connectors at those spots.. i just haven't had time to go back into it.

I can never fathom why someone would hack up the harness... I hope you get it straightened out... I also have a 93 NA, but I think my harness is ok... I just have lots of little niggling things... Like my mode selector can't seems to change the air from defroster vents to front vents or footwell vents :( Probably a motor.
