Re: Need part codes for 76 CJ7 TR Ignition Upgrade
 
There is no upgrade for the Prestolite ignition used in '76.
It's totally obsolete, and no one makes anything that will work with it.

If you want to upgrade to the Motorcraft distributor and DuraSpark module,
You will need to build or buy a harness for the Ford hardware.

The 'TeamRush' upgrade parts are as follows,

Distributor from a '79 Jeep CJ-7 with 304 V-8 engine.

Module From a '79 Ford F-150 pickup, with 302 CID V-8 engine.

Coil, E-core or Canister,
E-Core, '92 Ford Escort, Connector NAPA p/n ICC-1
Canister, '79 Ford pickup, all engines, Connector NAPA p/n ICA-102.

Cap Adaptor, Distributor Cap, Rotor, From a '79 Ford F-150 pickup, with 302 CID V-8 engine.

Resistor wire, Wells p/n F799, around $10 at Auto Zone.

You are on your own for the harness side of the connectors...

Here is the diagram,

Here is the harness I have for sale, $75 with out extras.
It's a direct upgrade for the factory Prestolite harness.

Delco alt. connector, $10 Extra. Comes with a fusible link for the master charging wire.
The '76 factory V-8 was equipped with a Motorcraft alternator and external regulator. If you plan to keep these, you don't need the Delco upgrade harness.

E-core coil connector, $15 Extra.
The harness comes with the canister coil normally.
I can install the factory E-core coil connector on the harness if you plan to use the E-core coil.

I was just about to something similar. I have a '77 CJ7 with a 304. I was wondering if the MSD 6 replaces the DuraSpark module. Would everything else be the same? What MSD would I need?
Teamrush, thank you for the wealth of information you so freely give on this board. I appriciate your help. Do you have a webpage or is http://www.geocities.com/swbjeep/ignition.html The best source?

The MSD 6 can either replace the duraspark or get its signal from the duraspark, it's your choice. On mine, I removed the duraspark module and wire harness and hooked the MSD 6 straight to the distributor.

The '77 has a Prestolite ignition. The Presto-it's-junk ignition was used on all I-6 and V-8 engines from '74 to '77.
'74-'77 Factory I-6 Jeeps had the Prestolite ignition, but the Delco SI series internally regulated alternator.
'74-'75 Factory V-8 Jeeps used the Prestolite externally regulated alternator.
'76-'77 Factory V-8 Jeeps used the Motorcraft externally regulated alternator.

You will have to scrap the entire Prestolite ignition if you want to go Motorcraft distributor and MSD module...

Find the ignition coil positive and splice it to the small Red wire on the MSD module.
Tape over the connector that went to the Prestolite module.

If you want to use the MSD 6 series for a module, I suggest you buy a distributor from a '79 Jeep CJ-7 with 304
V-8 engine, It will come with a Ford distributor connector already installed.
Expect to pay about $100 with a $50 to $75 core.
(use that piece of crap Prestolite distributor for a core and get some money back!)

MSD p/n 8869, Ford distributor to MSD module connector.
You will see the mating connector sticking out of the module.

MSD 6A module.
Large Black to the battery negative. No where else is acceptable.
Large Red to the battery positive. No where else is acceptable.
Small Red to old ignition coil positive.
Orange to coil positive.
Small Black to coil negative.
Tape over the white wire.(not used)

NAPA p/n ICC-1 E-core coil connector,
Connect the coil connector red to the MSD module Orange.
Connect the coil connector Green to the MSD module small Black.

Ford E-core coil, '92 Ford Escort.

Cap Adaptor, Distributor Cap &amp; Rotor.
'79 Ford F-150 pickup with 302 V-8 engine.
Use the premium cap and rotor with brass terminals.

Plug wires from a '92 Ford truck with 460 CID V-8
(MSD Red 8.8 mm wires are the best, and they offer a 'You Cut To Size' kit that is wonderful and worth every penny.)

That's it, you are ready to rumble.
