88 Pickup radio/console wiring help
6 Attachment(s)
Trying to figure out a jumbled mess of wiring behind my center console as the previous owner cut of the OEM connectors and twisted wires together to fit his stereo...
I've looked at the haynes manual, the service manual, and multiple aftermarket radio diagrams but it seems like there is no certain wiring diagram. I picked up a replacement pigtail off of ebay for the radio and I clipped some plugs from the junkyard. Any help or direction would be appreciated thanks! This is what I have.... Attachment 165299 Brown - radio ground Blue/yellow - 12V constant Gray - 12V IGN switch Green - illumination Attachment 165300 Red/green - + cig lighter White/black - GND Attachment 165301 I think these are OEM speaker wires, right and left, pos and neg, but i'm not sure where they come out so I'm going to wire the speakers into the connector with my own wire. Attachment 165302 I still have a red/black wire left over, which i think is a dimmer wire. Attachment 165303 and a black/white, white/black, green, and red/green. From what i've seen, black/white can also be 12v constant. White/black is ground, and red/green is 12v switched Attachment 165304 and finally i have what i think is a clock plug, i'm not sure why it has 6 wires coming out of it because the service manual only has 4 wires. |
The wiring is definately standardised. But I can't find any question marks in your post to answer any questions.
Guessing you've already seen this, and have the FSM? http://www.installdr.com/Harnesses/Toyota-Wiring.pdf That "extra" plug is "plug B", it contains the rear speakers and illumination ground. The speaker end of the wires are taped up to the harness under the dash near the speaker vent holes. If you wanna try again with questions and question marks it'd be a little easier to follow for me ;) Oh those four wires are probably the clock, colors match up. pg 1467 in the 88 FSM pdf. |
Thanks, really just wanted confirmation that what I've done so far is identified correctly.
So the 4 wires that have black tape on the end are for the clock, sorry I missed it. kinda obvious from pg 1467, I guess i was more concerned with plug B and I mixed up my pigtails and found the right one for the clock. Question is, what is that extra red/black wire for in picture #4? Radio dimming? Thanks for the quick response! |
Yeah think that is the ground wire for the lights. In my truck it was on a single spade connector seperate from everything else, but i have a 4 channel so had to attach it to the 2nd plug. It's pin N on the 4 channel system,or b4 depending what plug diagram.
You can test it, meter to power and that wire, voltage should change with the dimmer knob. |
