Well, I am hopefully going to be ordering the upgrade harnesses for the parking light and the headlights, and the alternator adapter for my 240z, so that I can get a stronger alternator. Are there any other electrical adapters and harnesses that I should consider? Most of my electric works except for the wipers and headlights, but I want everything else to be updated if possible as I want this 36 year old buddy to be more so reliable then the day it was sold. Edit: I also already got the electric distributor to replace the points.

Ok, so.... Where are some 5 1/4 inch speakers with a slim back and the mounting brackets for the speakers that go in the rear end of the 240z. I am going to see if I can start on my sound project so that I can at least listen to the radio with 2 speakers. I can't find the speakers with slim backs, and I can not find the bracket. I do not care about the wattage really. Just some nice quality.

Was doing some digging on causes of battery failure and what actually happens to the battery when its gone bad. I found a bunch of information about battery desulfation and how this can double or triple the life of a new battery or save a battery that appears to have gone bad. These guys www.batterylifesaver.com sell a device that connects to the battery and runs with out a external power source. It appears to have a capacitor and other circuitry that once the capacitor is charged up it spikes the battery with a pulse that over time dissolves the sulfation or will prevent it from forming on a new battery. I also found these guys www.wizbangplus.com that have one for $35 s…

I feel embarrassed saying this but I don't want to take any chances. The other day I was removing old vents and hoses so I can plug up the holes in the firewall to help avoid engine fumes. Anyway A couple of the hoses were attached to a metal box (behind the center console which holds some vents in the dash) and the nuts were held on tightly. I used wd40 to loosen the nuts and was able to remove them with no problem. As I attempted to remove the box It was caught between something and I was unable to see what it was (night time). I didn't notice that it was bare metal and the surface it was held on to was metal and as I wiggled it out it ignited the remaining wd40 residue…

I have an early 260z and I just swapped the alt for a zx one and wired it all in. I followed the instructions for the 240 and now when I turn the ignition to on my fuel pump runs and clicks. What do I need to do on the 260 to wire this alt correctly. I have been searching forever and everyone says the info is out there, but nobody posts it. Please help!

Is there a how-to for a wiper motor rebuild for the 280Z? I have mine out of the car, and out of the bag. Even though it's almost 30 years old, the motor case is still nice and shiny, but I don't think I want to go inside unless I know what is there. thxZ

I have a 1972 240z and the heater blower switch does not have 12v from the plug under the dash. My 240z chassis electrical schematic does not show a heater switch or wiring. Maybe I missed it. Where does this circuit get its power? Thanks Bob M

I just got this car and it has nothing running the rear lights. I was wondering if there is an aftermarket kit I can buy to hook all that up again. I don't drive it now because I really don't want someone to rearend me. The headlights are ghetto-rigged to a switch and are pretty dim too, but at least they come on. I was thinking a painless kit might work, but it seems like a handful to wire up. Any experience is greatly appreciated. Thanks, Jake

Hey, I'm looking to install a cut-off switch in my '70 Z. There's already a hidden button with wiring running out through the firewall and ending at the battery (though it's not connected). I understand my fuel pump is mechanical, so I'll probably have to go with an ignition cut-off, right? Any help would be greatly appreciated!
