Hey everyone,
Recently bought a 92 Eb gl which didn't have any rear speakers.
Having a EF donor car (still trying to figure out what will and won't fit), I took out the rear speakers to put into the EB.
The EB has wires for rear speakers from the head unit to the loom, but not to the rear of the car. What would be the best way to wire up the rear speakers?

Get a wiring diagram find the wires you need and then soldering and heatshrink so of your own wires onto them?

Or better yet, bypass the loom and run new wiring from the headunit directly to the rear speakers.

use some of the rear EF wiring in your EB loom OR if the wiring loom [rear] is same as EB swap em around??
