Ignition Coil Wiring - looking for a better way

Post by Theodore »

Am working on a 1990 Grand Wagoneer, with fuel injection installed on it. Admittedly, the wiring's a mess - am working on cleaning it up, with the eventual goal being to get another wiring harness & replace the hack job i have. The goal right now is to improve the drivability before jumping into something like that.

I think the ignition coil is a Motorcraft type, but am not sure - am wondering if there's some kind of connector that would enable a factory type click connection with terminals that would clean this up - make it look better, while increasing the reliability, and ridding the setup of butt-splices? As you can see, there's 3 wires that go to positive(+), and 1 going to negative(-).

Thats a TFI ignition. Its a very common upgrade over the stock setup. And, you can indeed get a connector that plugs into that. When I did a TFI on my J10 many ages ago, I used a CRT Performance kit, which came with the connector as seen here: https://crtperformance.com/shop/ols/pro ... box-gold-6

I bet if you call them, you can buy just the connector with the pig tails on it.

Thanks, Stuka. ? - do you know if there's a connector that i could use upstream that would take 3 wires in & 1 out to the connector recommended, that would get me out of butt-splices? So far, everything i see is 3-in/3-out.

Poking around, i've found a '3-way bullet connector' from Pico (Part number: 1882QT) at Summit: https://www.summitracing.com/parts/pco- ... gLrovD_BwE. The kicker is: i've not been able to find a 4-way that would clean the connection up.

Why not just solder it all and get rid of butt connectors and multicolored pieces of wire?

Think Ill take the advice & go that way. Had fought the idea of soldering given the difficulty of not having an extra hand, til I tripped across this magnetic third hand on Summit the other day, while looking for other stuff related to the Jeep project. Hopefully, itll be here to try this wknd.
