Head Unit Install

[DVSTRK]

hey guys just wondering if anyone knows wat the original r32 head unit colours match up with typical aftermarket head units, eg. red, yellow, black etc.

any ideas??

They are grouped nicely on the R32 head unit, there is 8 wires grouped together which are the speakers, and then 4 wires grouped which are constant, ACC, ground and illumination.

Grab a multi-meter (should have one before attempting anything electrical), and with the key out of the ignition, test each wire, one of them will be 12V+ (This is your cosntant, matches to the YELLOW wire of the new headunit).

Switch the ignition to ACC, re-check and there will be 2 x 12v+, the 2nd will be your ACC activation wire, this matches to the RED of your aftermarket headunit.

Now flick the headlights to park, and re-measure and you will have 3 x 12v+, the 3rd wire will be your illumination wire, this isn't always on aftermarket headunits, but if it is, it will be marked with ILL+, and this is what it goes to.

With grounding, run a new lead to a clean grounding point in the car, there is plenty of grounding areas in the R32 dash to ground off to, but sand back and make sure you have a clean contact.

For the speakers, they should be easy enough to ID the pairs, then it's a matter of temp connecting the pairs to 1 speaker output from the headunit to ID which speaker it is, then tag and mark them, and hook them up as per the colour/wiring diagram of your aftermarket headunit.

Good Luck
