I also could not get the newer style mocule to work so I swapped in the older style module. As far as the coil to distributer wire, I simply took the coil end off of the GM wire and crimped on the MOPAR end. Going to take the car for a spin tonight after dinner. I'll try and post a pic of my handiwork then.

Yeah, I'm going to try a few things tonight with the newer module and if that does not work I will buy the older module tomorrow.

Do you recall which ways you tried to wire the newer module?

Pics eh, that would be nice!

I took the pink from the modue and coil together with the the blue power wire from the ignition, the white with black stripe from coil and module together and the black and white wires to the distributer.

I was prepared to make the 97 Olds Bravada coil work with the LX-301 module but since the Magnecor wires came with an HEI coil end connector I went to Napa and got a Blaster 3. The Blaster 3 fits the stock mount perfect and the tall tower clears everything great. I was not too happy about having to go buy a new made in China coil but I made the mistake of mentioning the word HEI when I asked for the coil end. "Make it like an 97 Olds Bravada HEI". Live and learn eh?

The module heatsink took some grinding to fit the LX-301 but it looks pretty good. When I run all new wiring this winter it won't matter though since I think I will be hiding it out of site instead of right on my fender without a coil attached. :oops:

Sorry to say I can't help you locate a bracket, but I didn't even bother looking for one. I just cleaned up a spot on my fender (just got the dirt and grime off so it'd be smooth), put some Arctic Silver I had left over from my computer building days on the back of the HEI module and bolted the module directly to the fender. Isn't the cleanest looking solution, but it works flawlessly and the module never even gets hot to the touch. The fender is getting replaced anyway so I'm not even worried about the extra holes I put in it. I'll have a more permanent mounting solution hopefully this summer.

The black wires were a ghetto-fix ground loop just to last me until I have all my electrical stuff finalized.
Intresting setup, how is the relay wired up? (where?)

When the question first came up about the newer module (the one mounted on the heat sink with the coil) I tried it out on a bench test setup.
Spining the distributer by hand, I did have a spark. Since then I have done some more research, and have concluded that is not the module to use. The newer style module gets its trigger from the computer, and it is a 0-5 volt square wave (think digital signal). The mopar distributer puts out more of a sine wave type signal, and the voltage output will increase with rpm (think analog signal). I am using the early type module on the newer heat sink (requires minor mods to the heat sink).

Thanks, CS. I've edited the HEI upgrade article with your findings.

Don't know if this is the place or not, but here's another HEI conversion. Recently our old mopar module let go and we replaced it with an HEI module in a road side fix while at a show. I finally got around to finishing it up, putting it a neat case we sell, and neatening the wiring up.

Neat way to conceal the HEI module.
new number is 1-888-809-3835 toll free....

Little die-electric grease.

All mounted up and wiring neatened up.

The problem with the coil-in-the-cap style is that there is no where to connect the coil wire to. that coil discharges directly to the rotor inside the cap.

but the module in side the cap can?? I'm going to a u pull it to get connecters and whatever else I can :idea:

Correct, but we're using just a standard low resistance coil that we were already using with the mopar module.

The module is still inside the cap but I dont use that style module. I like to use the 4 pin module that has an external coil. The last one I pulled came off of a pontiac T1000(Chevette). The coil is a bit of a PITA since it is under the intake and held on with 3 bolts that only 1 can be seen. The wires are long enough that you dont need to cut or add your own connectors between the module and coil. That is what is powering my Swinger now.

If you look at the last post in the "HEI electronic ignition discussion" thread you can see a pic of what I have on my Swinger now.

Thanks alot for all the info, the sticky post it seems has all the info after all..I just needed the odd ball questions answered. Thanks for putting up with and helping out with the details. I have been reading this forum for some time now and but havent joined till now. what a great place and the folks seem like good people to hang out with..thanks again

new dist. should be into to day Im going to give the HEI a go.

PS. when I was about 12 Years old my uncle told me, the only way to test the spark on old cars is to hold the end of the plug wires while some one turns the car over..do I still have to do that?..... :shock: :D
