91 Comanche Ignition Coil Relocate

[HOManche]

Hey folks! I've searched the forum and haven't seen anything on this topic.

 

I want to relocate my ignition coil off of the block which makes the plug/harness too short to reach the relocation spot! My question is does anyone know of an extension cable that is available (male to female) or the type plug (p/n, style) our two pin ignition coils use?  None of the local auto retailers seem to have that in their info sections for a new coil.

Try going to a speed shop and have them make a custom coil wire to meet your length requirements.   A run-of-the-mill auto parts store only stocks standard OEM sized and length stuff.

Bring your coil into a parts store, see if you can find something that matches, and something to plug into it. Attach the two together. Then remember the skills needed to do that would also allow you to extend the factory wiring.

Solder and double-wall heat shrink tube are your friends.

I am confused.  Is the OP wanting a custom-length coil "high tension" wire, or an extension to the DC feed wires for the low voltage terminals on the coil?

I mean I can’t really answer that one for the guy. But considering he’s talking moving the coil off the engine block and asking about a two-pin connector, I was assuming the low voltage side. 
The other side should just be the same as a spark plug wire, yeah. Probably only way to get them individually as you pointed out is to go to a speed shop. Unless you’ve got a place that’ll sell you bulk spark plug wire and the terminals for it.

Depending on the new location, OP could get lucky and find his wiring somewhere within the harness loom. Now he might need to shorten the wires.

DUH.   I failed to read the part about the "two pin connector", and just assumed it was the high voltage side.

 

I agree with you in that the best/easiest/fastest solution would be to just extend the existing wires by solder and heat shrink tubing.

I did this, used a couple of solder seal wire connectors to get it done. It was a PITA, since you don't have much wire to work with if you don't want to unclip the harness to get better access to it. Moved mine to the firewall:

Yep, DC power and return. Using the K-suspension bracket that mounts to the water bottle. Drill a couple of holes and relocate the coil away from the block. What was Chrysler thinking? Electonics+Heat=shorter life or failure. I can find the coil pigtail but was trying to avoid cutting off the OEM connector for splices and yes, there is not a lot of wire to work with.

What brand is your current coil? 

[HOManche]

OEM Mopar that has unknown years on it so worst case around 33 years for a '91 that shipped in '90

Except if the OEM coils were made by Marelli.....VERY failure prone.

Magnetti Marelli?  You mean the Italian Lucas?

True that!!
