radio wiring

Postby wadles99 » Wed May 28, 2014 4:19 pm



All,

I purchased a 1984 Goldwing Interstate GL1200. When I purchased the bike it didn't come with any of the OEM radio, controls, or speakers. I am trying to put an aftermarket radio on the bike but am having difficulty determining the wiring. I don't have a fairing wiring diagram and any of the OEM radio schematics I have found don't label the wires or color codes that honda used for the harness. I have some harness wires stuck up under the right side fairing box as I was told that these were the wires for the radio. Any help I can get in determining the switch 12v, the battery 12v and the ground would be very helpful. I can wire the speakers in directly from the radio so those shouldn't be an issue since i'm not installing passenger speakers. My radio has a diagram as to wire labeling so the radio side isn't an issue.

thanks

Bill

Without seeing your harness,I can only speculate...however.
A cheap test probe would help.
Second.Honda wiring harness usually denotes dark green as ground,brown or black as switched,red is battery.
You should be able to locate the faring plug for the radio system.it should contain the ground,switched and main power you need.
Also look at every radio related manual you can.some are in the above manuals section.Even it isn't related to the radio,check the pictures for tell tale plugs,color of the plugs and individual wires.
As a last resort,you could run your own wires direct from the fuse block.

thank you for the information concerning the wiring colors. The plug that I am assuming is for the radio is a 4 pin quick disconnect plug that has a beige/white color. Color of the wires in the plug are red,green, brown, and i believe a green with white stripe.

I will give your suggestions a shot.

Do you have a test light or volt meter handy to identify voltage?
I'll see what else I can find too
It looks like light green/blue is switched ignition
Red is 12 volts and green is ground.
This is from a red faring plug with 3 wires in it.

Okay. I will take a meter home from work and take a look at the voltage levels. I will verify the plugs and post some pictures tomorrow if I cant find anything with the volt meter. thanks for all the help

Well I didn't get the photos but I was able to figure out the wiring with a meter. Unfortunately the wire that should be the hot wire (red) from the battery isn't hot. None of the wires in the harness have 12 volts present with the key off. Looks Like I get the joy of having to track down a wiring harness issue. thank you for your help yesterday in getting me started on the right path.

Pick your fight.sometimes it's easier to run a sepetate wire.Fused at the battery.

That would definitely be easier. However it looks like some previous owner went in and removed some connectors form various parts of the harness (i.e. 3 yellow wires to the left side of the battery) and just taped them up with electrical tape. Figure this might give me the chance to clean up the harness a bit.

The 3 yellow wires should be soldered and then insulated.
A side note: I do recommend some kind of digital volt meter be added to the bike so you can keep tabs on the charging system.There a cheap add on.
Is seems most breakdowns are out of town and related to a dead battery.A visible meter can forewarn you and give you time enough to get to a safe place.
By the way...how's your timing belts.???Old??

I am very sure the timing belts are old. I haven't replaced them and neither did the previous owner. So it is possible that they have never been replaced. And yes my plan is to go through the harness and isolate all the cut off wires so that there is no possibility of shorting. I have a couple of wires in my taillights that are just bare copper wrapped together and electrical taped. So it needs some work and should be a good winter project as I tear the bike down and have the pieces repainted.
