Resolved 2G OHM Harness Question

[cherryfromthe405]

I have 97 GSX hear with OHM engine harness and fuse box relocation.
I've had a difficult time getting ahold of OHM and searched as much as possible.

I have these 2/3 wires on the RH side interior harness and its labeled ALT RLY (see photo below) brown and blue wires and black wire

Then the white connector on the LH side. Has 3 wires going to it but 8 pin connector. Its not labeled

Know where these go?

This from OHM website. Same wires for ALT RLY. Mines just doesn't have the connector.
Does anyone know where this plugs in?

why are you asking? does something not work correctly?

those connectors and pins have nothing in common with the factory 2g wiring

if you have to ask what they are for, you need to remove the harness and check continuity to connections in the harness to see where those pins come from on the other end of the harness.

for all we know the ALT RLY is the alternator relay, or its the, alternative relay for accessory power.

youre going to have to remove the harness and find the matching colors on the other end of the harness

I am asking because Im install the harness and cannot locate where these 2 go.

I believe the Alt relay was a 95-98 only thing. It's actually not a relay at all but a resistor and diode. In the original air harness it should go near where the original air filter would have been. It's a little box shaped thing that plugs into that. I believe it's only real purpose was for the light on the dash.

The 8 pin connector might plug into the back of the interior fuse box, as seen in the background of the photo.

I could be wrong on both of these things so double check.

Thanks for the info.
The ALT RLY has been resolved. OHM didn’t put a connector on the end and kept the relay. Have now ordered a relay and still no reply from OHM.

Now to just figure out where this last connector goes. I checked out the fuse box again and doesn’t go there.

Are you sure it doesn't go into the back of the fuse box? I believe there were two plugs that went into that, and they were really tough to get to because you can't see anything back there.

I have 3 plugged into the back side of the fuse box, 5 on front and 1 on the side. All plugged in and no more for this connector

Thanks everyone for help. I got it figured out. Its connector C25. Here is a picture of what it plugs into.
Thanks again for all the replies.

What did you end up using to connect the alt rly wires. OHM customer service is questionable and I want to see if connecting this will maybe fix my a/c compressor not receiving signal from the harness side.

Wouldn’t they just plug into a generator/alternator relay?

 

[cswindel]

Well thats what I was thinking but I have been messing with the wires, which btw route to right under the glove box with nothing to hook up to in that area besides a relay behind the radio if thats what it goes to, and I found:

The black wire is at 0v with battery on and ignition off but gets full 12-12.5V once ignition on. So if it was to go to a relay this would be what I would assume to be the pin 30 constant power wire

But the blue and brown wire combo give off a small almost 5v power with battery on and ignition off. With the ignition on it gives about 11.5v. Im assuming one is a signal wire.

But why have 2 ignition based power wires for a relay hook up and why have, possibly one of the two in the same connector, be a 12v to the apparatus it connects to?

I was going to split the brown and blue wire to see which gets the voltage and do a continuity test with the blue one because there is a blue wire going to my ac compressor

Edit: I should probably provide more background on my a/c troubles but I dont think this is the thread for that. But I suspect its the harness because its not the first problem its caused for me

I could see OHM moving the location of the generator relay. There’s no saying it has to be in the engine bay. And, you know, because racecar, as little in the engine bay as possible. It also reads like that’s what the OP did in post 6.

Here’s the diagram. I tried going off memory making my suggestion, thinking those wire colors sounded right. Obviously, I was off and the wire colors don’t match.

But, with the battery disconnected, you could back probe to see if the wires you have end up at the specified locations. Looks like the alternator wire might be one of the easier ones so does either the blue or brown (I’d try brown first) have continuity with the alternator connector pin 3? If it is for the generator relay, it won’t have anything to do with your A/C, unfortunately.

Well you were darn close! The brown wire for the ALT RLY has continuity with pin 2 of connector A-03. Unfortunately, the blue and black wires dont have continuity with any wires in that connector and none of the ALT RLY wire have continuity with any wires in the A/C compressor connector.

Well good news is that solves that mystery and I can forget about that bundle of wires again and I can cross that off my A/C no signal to compressor checklist.

Time to dive back in the threads of A/C and maybe just try jumping the two wire connector together for the cabin temp sensor. @19Eclipse90 would it be alright if I PM you in the event I hit any hang ups? Thank you for all the help thus far! This community is a big part of why I love owning this car
