Armand - I’d like to hear from you on your engine start/run results by you plugging in the new rtr dist in your Javelin with its current wiring. Would like to see if you different results (runs smooth, no popping/shuddering) or the same as I experienced thus you needing to follow my wiring.
Pls let us know. Thx. Greg

Holy bajesus, it worked!! Someassemblyrqd, thank you so much for the drawing. And then dumbing down the directions so that I could understand it. I really appreciate it, let me know where to send the check.
 The car starts and shuts off, and the tach works. I tried to spiffy up the wires a bit. Now, only 2 more problems(maybe 3) I didn't know if I should ad on to this thread, or start a new one. So I'll start a new one, it will be titled, ALT Light Still On. Help me if you can. Thanks again.

Someassemblyrqd, I'll try to keep that in mind. This is one of those projects that drags on and on cuz so much other stuff gets in the way. Right now the problem is, it's way too cold in my shop. Anyway the plan is to break in the cam on an engine run stand. So I'll wire it pretty simple, just to start and run. I may try to borrow a suitable tachometer if I can. But I'll try to keep you updated. Armand

Well I’m reading and have copied Msd / factory Tach wiring diagram that has been drawn
Have a couple question The car I bought a few years ago Had a HEI install distributor I’m putting in a MSD RTR double yellow wire on the (I)sided whoever wired in the past Some one removed these wires They do not exist anymore! So can use the pink and yellow installed on the (I) terminal As they are tied together anyways??? You also show 9 volt resistance wire . - Tach + coil Or did you install a resistor in-line to accomplish this?? Any suggestions welcome :)

Hi Greg,
I've read your post with great interest as I have an MSD 8519 in the box, an MSD Blaster 3 coil 8223, and MSD 8.5mm wires, all ready to install. Several other posts indicate that I also need an MSD 6 or 7 series ignition box. Is that the case and if so, how is that wired into your diagram. I was under the impression/misimpression that the components I have already purchased would do the trick. Please let me know whenever you get a moment. Kind regards, Ken |
