The PO of my vehicle did me no favors with electrical. The wires behind the heater control panel are a total mess. So I am slowly working on solving what's what and cleaning it all up. For a while the blower motor worked, and now its not working for me. The wires around the heater are all jumbled up, and I would love to know where a good clear resolution wiring diagram can be found, or ideas for me. I also have been going slightly nuts trying to find the hookup for the switch for the rear defrost. They just come out of the center console, and i cannot for the life of me find where they plug in. THank you for the help.

Took off today and found that the passengers side headlight is dim. This is strange and sudden, as I have installed the relay upgrade as well as headlight upgrades, and have had no issue for almost a year. Would love to hear some ideas on what this could be a result of.

I am in the process of putting my dashboard back into the car (1973 240z), I didnt label the connections (bad mistake, I know) Everything seems to work, except my dash lights. My current issue is that I keep blowing the parking light fuse (third one down from the right, MSA fuse box) when I turn the dimmer switch. Any suggestions on how I should approach my issue?

Hi, I'm rewiring my car for a Chevy v8 swap. I've got a lot of it figured out, but need some help. The car is a 1973 car and I think it used to be manual. This first picture is of the main harness below the battery at the firewall: The red arrow is pointing to a solid yellow wire that goes to the voltage regulator plug. It is spliced together with another yellow wire at the plug. I am removing the voltage regulator. This yellow wire comes out of the firewall along with the black/yellow wire which goes to the starter. The two wires are sheathed together. The green arrow points to 4 wires. Two are red/black and two are green all with bullet connectors. These we…

Hello, I purchased my first Z car yesterday and while it may be kind of rough, the guy told me that it was running when he parked it. Unfortunately that was two years ago and it looks like he cut the cables when he took the battery out, or the battery was stolen and all of the cables were cut. I installed new terminals today and I am just trying to see if I can get the car to start. Unfortunately, it looks like the car was replaced with an after market electric fuel pump and I have no idea how it’s supposed to work. I have some questions and my hypothesis, and I have presented it with pictures and a diagram. I am just wanting some conformation that what I am presenting…

Hello crowd I know its been a while but I have been trying to get #6333 back on the road again after a main harness fire back in 2005. I was able to scavenge an exact copy of a good unmolested harness from an early 1972. #6333 was built in the spring of 1970 but the harness is the exact same. After many weeks of of cleaning the harness up an soldering some ragged spots and recovering it I have it installed and all connections completed. I put a battery in it this morning but nothing inside works. No lights, the starter does not turn over, no brake lights, NO NOTHING. Can someone shed some light on something I may have missed. At the moment I am at work and it is really bu…

I picked up a blower switch for my 72 at a junkyard. The medium and high positions shorted out, but low wouldn't pass any current. Taking it apart (CAUTION: SPRINGS AND BALL BEARINGS!) I discovered what I took to have been grease liberally applied throughout. I cleaned it out, because if it were grease, it had begun the process of reverting back to its natural state. It makes sense to me that the strictly mechanical ball bearing side would use a bit of regular (lithium complex) auto grease, but is that what was applied to the electrical contacts? Or a different sort of grease (a dielectric?)? Or could I lube it with a 'contact cleaner with lubricant' that I've used o…

Hi! I was having some trouble with my left headlight being really dim compared with the right hand side (yet according to my multimeter, the connection was still pulling 12V), so I looked around and found it might be a fuse problem or a ground problem. I looked here: http://www.classiczcars.com/forums/electrical-s30/4684-fuse-box-73z.html Found the fuse that I needed to check, the upper right hand one. I pulled it and just for kicks, turned the lights on. Nothing changed. I still had the dim left hand light. Um wat? Put the fuse back in after dusting if off with my fingers, the light is now 100% But I think that the fact that the left hand light still worked, albeit at on…
