I知 just about finished getting my 74 Javelin back together. I am having a bit of trouble with tying up the loose ends of the wiring harness I installed. Specifically getting the Tach/Clock working, the Voltage meter hooked up and wiring in the neutral safety switch. The wiring harness industry caters to the big three and AMC mixed and matched from the big three making retrofitting an after-market harness a bit of a challenge.

The harness is set up for a tach. I have connected the tach wire to the coil but get no reading on the tach when I attach the wire inside the car. I知 not sure if the Tach is bad or I知 not doing something incorrect. Any idea how to test the tach and wire it if it is okay.

I have no idea how to hook up the voltage meter and there are not provisions in the harness to connect it. Any ideas on how to wire the original meter? It is not tied into the instrument cluster like most of the Big three. The meter has two posts I assume are positive and negative but I do not know where I should make the connections.

I知 also clueless on how to wire in the neutral safety switch. The car has a 727 tranny with the standard chrysler NS Switch attached to the tranny. I知 not sure how to wire in the relay into the ignition system and the NS Switch and get things to work. I do not have any way to test the old relay and would perfer to use a new relay. The tranny has a new neutral safely switch.

BTW, its an ampmeter, different than voltage, a lot of people dont hook them up since they were kinda flakey

Another option for clock, tach, and gauge restoration is Instrument Services at http://clocksandgauges.com/ or see http://www.amx-perience.com/AmericanMotorsForum/showthread.php?t=23
I did the clock kit and it's still working great. Don't know about their other kits and I'm not saying one company or kit is better, it's just another option to look at. And they cover most all makes and models.

I must be an idiot because that makes very little sense to me.

Thanks for the info on it being an ampmeter. I found the wiring for it in my manual but I don't get it either.

I guess I need a picture/diagram of what exactly to do.

I looked at the the link Big Bad AMX posted and tomorrow I will call them and get a quote on converting my ampmeter into a volt meter.
