Joe, the purple/black wire is the tach wire. It now needs to come off the MSD box and go to the tach directly.

The tach wire in the dash is a better looking prurple/black due to it's being protected from the elements for so long.

For my fuel pump key on power I'm using a wire off the stock relay board with no ground jumper. I use the front/right terminal on the F.I. socket. ( front right being closest to driver and engine ).

Mike, this is a bit odd. Same weekend. (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif)
So, which wire gets the diode? The D+ into the relay board or the keyed 12+ power to the MSD which is shown to be the original coil+ wire?

From the diagram on pg 8 of MSD manual it looks like the exciter wire needs to be diode protected so the small amont of voltage will will no longer activate the MSD which has it's own 12v constant power source.

MSD calls it a "100V/1A diode".

So can just place the diode in-line before the charge light in the dash behind the guage?

i believe you want the diode inline with the switched hot to the box (form your IGN switch) thats what my bok says anyway (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif)

Gee or read the manual they actually tell you that you may need to use an early Chrysler ballast resistor as part of the install. Had to do this on the 944.

put a set of male and female terminals on the diod and do it right at the indicator is my guess (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) (no cutting or splicing necessary if you solder termianls onto the diode (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

50/50 HUH? Not so good odds.

I NEED the real story! (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif)

I want the electricity to go one way, to the bulb, right?

Got it!

Crimped on a terminal to each end with heat shrink between 'em. Works great. No more run on. (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif)

Still need to open up the plug gaps (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif)
