Google search. It’s a small 1”x1/2”x1/4” (ballpark) silver rectangular electronic piece with 3 flat metal electrical connectors. It plugs not the back of the rally dash circuit board. It powers those 3 gauges and drops 12V power to 5V for the gauges. They fluctuate and burn out. Electronic...
I'm not concerned with a purely original look. I took both the blue & brown wires, coming from the bulkhead disconnect (big bunch of wires & 3 big plugs on firewall), that go into the ballast resistor and splice those two together + also splice in the blue wire coming out of the ballast...
Pink is always hot. As mentioned, check the fuse. If worse comes to worse, you can temporarily run a fused hot wire to where the pink wire connects to get your brake lights working
My 2-cents? I've heard problems with newer orange boxes. The only time I burned up Mopar ignition boxes is when I pinched the main blue hot wire under the corner of the intake manifold (short). Having said that, I've personally run MSD boxes (no ballast resistor) for a long time now with very...
I am no electrical whiz...but I think the answer to your question is "yes". Somebody jump in and correct me if I'm wrong, but I "think" the ammeter still acts as a main power connection, even with the "bulkhead wire/ammeter bypass" wiring modification.
Unhook the battery first....then run a...
This has been INCREDIBLY helpful!!! If I'm understanding this all correctly (?)
1. Not all LED 1157's fit. I kind of figured this out when I looked at superbrightleds.com. They all had the same socket, but different sizes. 1" diameter sounds about right. superbright had one 1" dia. LED bulb...
I'm working on something similar right now. 1970 has a key/headlight buzzer...one buzzer, two functions. I have not seen them reproduced and the NOS ones I've seen on Ebay were about $125 range.
OK, I almost understand....if I run a whole fuse block to be hot during start/run off a signal from the + of the ignition coil, I don't need any additional relays for things I have running (fused) off that fuse block, correct?
Whoa...it's a long list and I'm trying to add up amp loads...

1970 Road Runner - I'd like to make my tail lights & brake lights brighter. I've been looking at some 1157 LED bulbs and searched the forums here. I saw a reference about "LED turns signals won't work". So my question....is there a LED 1157 tail/stop light bulb that can be installed in a 1970...
That is WAY over my head. I know almost nothing about wiring. I did install some type of "ammeter bypass" a few years ago so power doesn't go through the amp meter (I think that's what I did) and it goes through a really big fuse instead (100A I think?). It is a 1970 plymouth road runner with...
