Here's the deal. Switching to Vacuum advance distrib. to eliminate computer because of the Edelbrock 600. One problem, there are more wires on the oem distributor than are on my Mallory. I assume because some are for the computer? I need help figuring out which ones I need to keep hooked up. Here is what wires I am dealing with:
OEM: 1. C-, brown, hooks from distr. front to cap.
2. GRD, Blk, hooks from distr. front to cap.
3. B+, Red, hooks from distr. front to cap.
4. TACH, white, hooks from car-probably tach- to cap.
5. BAT, hooks from car-probably battery-to cap.
* And there are four wires that hook from a harness to the back of the distributor. colors(brown w/blk stripe, pink w/ wht stripe, white, and blk w/ red stripe)-------could these be the computer wires?? Do I need them?

The Mallory wires are as follows:
1. Red, hooks to ballast resistor 12v side
2. Brown, to engine ground
3. Green, to coil (-) terminal.
I think these 3 wires replace the 1-3 OEM wires. Does B+ on oem mean the same as ballast resistor 12v?

Also I would like to keep my tach wire hooked up so my tach will work.
I know this is a lot of help to ask for, but I really want to get this right. Can anyone help? Thanks a lot

 

come to think about it the one and only mallory i ever had needed and adapter from mallory to work. i had to cut the factory wires and splice into the adapter.

 

ED,

I contacted Mallory's help website. I didn't find an adapter on their catalog, but their catalog wasn't very impressive. I told them my story, so they will probably know if I need an adapter, and if they have it. I just need to find which wire is my 12v ignition wire. I think mallory can help me with the rest.

-----Anybody with an LG4, 4bbl, out there know what the 4 wires are that plug into the back of the distributor??----- They come from a harness whose wires run into a loom and route through the the pass. side fender.

Thanks for the help.
