Radio Help on M135GX

[jmessing]

Hello Everyone!

We recently bought a M135GX and didn't buy it with the radio. I recently picked up a radio and a kubota wire harness to plug into the slot where the radio goes. Here is where I ran into a problem though.. The female plug coming from the tractor does not have the RED and YELLOW Ignition Power and Constant Power (respectively) so where is the radio supposed to get power? Secondly when I ran a direct cable to the battery (just so i get atleast get it working) There was only the ground cable, power antenna cable, FR speaker +, FL speaker +, RR speaker +, and RL speaker +, plus one other one which I am drawing a blank at the moment. The tractor only has 2 front speakers so the 2 wires that are for the back are useless. and when I plug the two front speakers up only the FR one works...What am I doing wrong?! Any help at all would be greatly appreciated! Thank You!

Edit: Also the adapter we bought (the one that you attach the radio wires too then plug into the tractor) had an ignition wire and a constant power wire but they didnt lead to any pins on the female tractor adapter so hooking them up did nothing :/

Does your adapter have all the necessary wire to run the radio? If yes, cut off the Kubota end and wire the radio as you see fit. Use the adapter end as a new Kubota end, that way you can unplug the radio anytime.

Adapters are like instructions, are like recommendations, are like opinions, amusing but worthless.

It's not very common that a radio uses ground and only + wires for the speakers, How are you determining the wires are just +'s.
Most radios require that you use 2 wires off the radio to each speaker.

Yeah, I didn't really catch that.......

There is no common ground......each speaker has it's own pair.......+ and -

What I meant to say was the Kubota adapter that plugs into the tractor only has speaker + wires. The radio has all the normal wires.

So the adapter had IGN, Const Power, power ant, and 4 speaker + wires but no speaker - wires. But where the IGn wire and Const power wire were on the adapter there was no corresponding pin on the tractor female end so ill have to go through all the wires from the tractor and find out what is the IGN and Const power then the 2 + and 2 - wires for the speaker. Sorry i'm not very good at explaining what is in my head!

I doubt your harness on the tractor has a constant power wire anywhere past the ignition switch, I doubt there is anything that was designed to run constant. You'll need to run your own wire (fused) from a source. It only maintains the memory and clock.

I suspect you will have 6-8 inches of wire from the back of the radio to the radio plug, you may have to cut off the plug and attach spade connectors to each wire and do the same with the tractor side. That is what I did with my '88 Jeep as the new radio plug was not compatible, similar to your situation.


All the radios I have dealt with have a label indicating what wire, color and stripe, go where, the only thing you need to identify from the tractor is L and R and ignition source......and of course a ground, of which you could create your own and run it with the constant wire.

Also, check your fuse box, you may have a space for radio that has no fuse since it did not come with a radio, that might be the reason you have no power if it was designed for a constant power source.

Looked at it today and got it fixed within half hour. Took a voltage meter and found out what pin was the ignition in and constant pin. After that just had to figure out the speaker wires which wasn't hard. Thanks again!
