Adding extra wire to aux switch wire in engine bay

[ocsdtans]

Can someone please help me in getting the right automotive wire type to wire IAG interior lights. I need to add extra + and - wire from IAG harness to go through fire wall to aux switch wire in engine bay. A don't want to plug the IAG harness to fuse under steering wheel, I want to use aux swithes to turn lights on and off.
Any help would be great, Steve

There's already some wires behind the glove box.

Some reason you can't use these?

It sounds like you might have the old style interior lights. We have since moved to an interface with the rear dome light, tying in to the Ford linbus system. We sell the adapter separately if your are interested in simplifying the install. Available on Amazon as well if you prefer.
