Ive spent the night trawling the forum, but the concensus seems to be that people totally remove the active system if swapping the HU.

Im assuming its active that ive got, it came with a Toyota 13702 HU in the boot.

Ive ran a meter off the Cig, which gets me 14.4 ok, but 0.7v off the red when earthed

- it makes me think that I've got an active system.

Can the wiring be configured to run an aftermarket HU, or do I need to pull the wiring back to each door, and also track a fixed 12v, and ign 12v?
Any help appreciated
