Default Relocating a coil on a 1st gen ram
by psycobilly64 08-09-2011, 12:31 AM

This is a write-up on relocating an ignition coil on 1st gen Rams. This can also apply to other Dodge vehicles with the coil mounted on top of the intake. I had to move mine since it would overheat after about 20 miles, making me have to pull over and sit for 15-20 minutes to let it cool down.

Step one is choosing the new mounting location. I decided to mount mine on the passenger fenderwell in front of the washer bottle.


Step two is unbolting the 2 bolts holding the coil mount on the intake.



Once you have the coil removed from the stock location, remove the wires from the coil (both electrical feeds and the coil wire). Cut the two electrical wires and splice in wires long enough to reach the new mounting location. These can only be put on the coil one way, so as long as you only cut and splice one at a time, you'll have no issues.

Mount the coil in your new location with either self tapping screws or nuts and bolts. You may have to bend the mount, or spend the money for a universal mount.


Once the coil is mounted, you can hook up the wires and make your new coil wire. I used a kit from Accel that came with a 60" long 8mm wire and multiple ends. The kit also includes a crimping tool for the ends that requires the use of a vise. Decide which ends you need by looking at the coil wire you removed from the truck. Cut the wire to length and crimp on the ends following the directions in the kit.


Once it is wired up and the coil wire is attached, start the truck and make sure it's running right. If so you can tape up the wires, zip tie the wires out of the way and you're done!

Thanks man. It only suggests you use a vise. I managed to use a set of lineman's pliers to crimp mine on. Not as pretty, but you don't see the crimps anyway . The wire kit I bought was only 16 bucks and some change from my local Advance Auto and I had some left over 12ga wire from the reg mod for the power leads. If I bought everything for the mod it would have been around $30, so it's a pretty cheap mod.

It is def that! I will be doing a relocation as well soon but ironically enough where your mounted your ign box on your firewall was where i was considering moving my coil to. Then i shouldnt have to worry about wire lengths while at the same time gaining the same advantages as your relocation. Either way it still moves it from the hot area it is currently sitting in.

my 91 originally had the coil mounted to the firewall. i don't see anything wrong with the coil being mounted on the intake but billy's truck is different. he is running 12volt straight to the coil because he could not get is to run with a ballast resister. that is why it can use as much help keeping cool as possible.

Ya that's the problem with re-engineering a factory system. As soon as you change one thing, another issue pops up. I think I've finally got it sorted out though!

My hei coil is mounted in that location, but since my dizzy is on the side of the block, i dont need a huge coil wire. the module and heatsink are also mounted next to it, i had to put a small computer fan on the bottom of the heat sink cuz the first module fired when it got into the high 70's back in july. Its been in the 90's lately and no problems yet. Have the power for the fan hooked up to the positive for the coil with a 3 amp mini fuse. Works great! Maybe you could strap a fan to your coil
