Hacking up EDIS ignition wires

Post by -nick »

Before I destroy a perfectly good set...

I can just cut & crimp generic ignition wire terminals on to the ends of these, correct? I need to resize the wires considerably.

Also, any tips on where to find terminals?

cheers!

The wires on the EDIS connector are appropriately sized for the purpose
they are intended. Why do you need to resize them? I don't recommend
replacing the terminals, solder and heatshrink onto the existing wires.

I need to resize wires too. It is no suprise that two sets designed for a euro Escort do not fit my Rover V8 correctly.

I've never modified any plug leads, but understand that it is fairly common practice with US "high perf" stuff to make the leads to your own length. Getting an effective crimp is likely to be the limiting factor.

I made my own EDIS plug wires because the ones from the Escort donor car were way too short.

I bought some bulk copper-core plug wire from a parts store, cut it into pieces of the necessary length, uncrimped the connectors from the EDIS wires, and crimped them onto the new wires.

Simple as that.

Hey guys,
I found out that it's really fairly easy to shorten the stock EDIS wires. You can get to the terminal by pushing the wire through the coil side boot (put a little grease on the outside of the wire to help it slip through). Then pry the old terminal off, and cut & crimp like you would for any ignition wire.
