Hi
Just about to fit a new head unit, but as the previous owner had the original Toyota head unit and a cd head unit both wired in together, all the original plugs have been cut off and I dont want to trace all the wires thru the relays that have been fitted!!!!
Does anyone have the wiring colours for these so I can just cut everything out and start again????
Cheers
Peter

Re: MK1b Radio Wiring diagram (wire colours - head unit)
As there have been no replies I thought I would post an update to benefit anyone doing searches in the future.
Here are the wiring colours of an mk1b radio system.
NOTE I did not trace all these wires back myself, I just used the coding from the cable adaptor I had from my MK2, therefore I accept no responsibility if these are wrong (but my radio is working fine)
Front left +ve : Pink, Red dash
Front left ve : Purple
Front right +ve : Light Green, Red dash
Front right ve : Blue
Rear left +ve : Black, Red dash
Rear left ve : Yellow, Red dash
Rear right +ve : Red, Blue dash
Rear right ve :White, Red dash
Constant supply : Blue, Yellow stripe, Red dash
Switched supply : Grey, Red dash
Earth : (Sorry, forgot to record this one)
Lights : Dark green
Ariel : (2 wires on car both connected to same radio wire)
a) Black, Red stripe, Red dash
b) Pink, Blue stripe, Red dash
Hope this is of some use to someone in the future
Cheers

IT sure will when I get round to installing my changer system (get the car on the road first )
Re: MK1b Radio Wiring diagram (wire colours - head unit)
If you still have the original Toyota plugs fitted (and not some weird and wacky set up using 2 relays like I did on mine), then just buy a adaptor cable (halfords), it will make life a lot easier and quicker, also helps if you ever have to change back.

Cheers, just looked at what you sent and our colours matched up, phew, I wired my radio up correctly.
As I'm sure this is the same for the MK2 you should get your diagram uploaded to the knowledge base as I think others will find it useful.

Re: MK1b Radio Wiring diagram (wire colours - head unit)
Is the wiring diag the same for my radio/cassette Toyota PLL syntyesised LW/MW/UKW Receiver 5199 ? My car is a mk1 1985. I can't see any rear speakers, do I have them or were they an option?
Plugs have been cut off. I have plugs for the radio/cassette. But colour of wires does not seem to match. Haynes manual states +ve is Light Blue. But this wire on the cut off plug when fitted to radio seems to be connected to the metal case (0.5 ohms). Case is ususlly earth. Expect fuse will blow if I connect +ve to the Light Blue wire.
I assume the diag of the 4-way and 10-way plugs/sockets is looking at the back of the radio/cassette.
Is my radio from a 1985 car? Thanx

Re: MK1b Radio Wiring diagram (wire colours - head unit)
I'm not sure about the Mk1a wiring, but I'll check. Rear speakers were only fitted to the MK1b, 1a had a sub under the drivers seat.
Black is not a colour ! .... Its the absence of colour

Cheers, i'll be able to sort mine out tonight just spent all yesterday trying to sort it out, and about an hour to find this.
