Voswitch Apollointech Question make a negative trigger

I have recently purchased an Apollointech (voswitch) switch relay.

Does anyone know if it is possible to convert the relay box to a negative trigger rather then a positive trigger.

I wanted to make it sleek and hoped to changed the relays in the box if possible...I did not want to buy the door lock polarity invertors and put them in between the lines from the KAC-001 unit that I purchased. I know this possible but was hoping to do it directly at the Voswitch box under the hood of the Jeep.

Sure.


Cut the positive and negative (trigger) traces on the pc board and reverse the polarities. Right now the negatives are constant and the positives are switched. You need to reverse that.

That sounds some what easy...I am hoping. Can you be a little bit more descriptive...Where do I send your soda/beer money!

All you have to do is fix it so the switches are on the negative side of the relays as opposed to normally being on the positive side

I am thinking it is the red 12 v coming in wire circled...switched with the black. But that does not sound right.

Are you looking to make the actual switched negative trigger or the device controlled by the relays?

Anyways you have to look at the PC Board. To change the relay contacts, would make more sense to me and might be a bit harder. Changing the switches themselves don't make a lot of sense to me as the switches only switch a very small amount of current.

What you circled is the remote cable from the switches that operate the relay coils. That has nothing to do with the relay contacts themselves. What you need to change is one of the actual relay contacts, usually pin 87 or 30 from a positive feed to a ground feed.

Those should be fed from the + marked cable and that probably feeds those fuses which then feed pin 87 with pin 30 going to the screw terminals.

yes I think you are right as Alpine said something similar to this, without them looking at as they said their x409 could not be changed as easily.

the relay has both pin 87 and 30 on it.

This might be really easy or it might be a darned impossible task. What I can tell you is it isn't as easy as switching the +12v and ground leads going into the circuit board. It would be nice if you could get both a PC Board layout and a schematic. That would be a real help in determining the complexity of doing what you want.

I emailed both places on voswitch that it says to get the diagram or ask if it could be done. I just have not got a response back yet. as this is what the radio place wanted from the switch.

Never recieved a response from apollointech...and I'm just not savvy enough to do the board switch that was suggested. So to close out the thread I used a door lock polarity inverter. Which goes in between the setup to make a negative trigger a positive trigger, which anyone that crimp a wire can do.

Probably a good idea. Modding the board incorrectly would get really expensive, really fast.

Just add a relay between the Apollo and the load being switched?

I didn't even think of that. That would work.

A $5 relay can help switch the negative instead of the positive, or change from NO to NC. Or both!

I feel like there is an easier answer. Pull the fuse for the relay. Flip the switch on if it lights up and use a meter to figure out the hot side of the fuse holder. Run a jumper from ground to the side that is not hot. Then the + terminal for that output would become negative. Then get an inline fuse holder and put that fuse on the + terminal and run it to the device.

So, I asked a similar question to the Radio Installer....and they said kind of no. I do not know the exact answer. however. I am live within 10 miles of the Alpine Corporate office and called them and the place that I bought from RSKT Radio Speakers Knobs and Things said to do what I did...and they each could not come up with a quick convenient solution.

I do have trust in RSKT as they have been very upfron and so has alpine. However I am the guy with the Jeep. So far the suggestion by RSKT has worked out just great, the only issue is the wiring of the light on the mirror does not always turn off...I assume because the wiring is so minute.

It CAN be done several different ways.... including the relay idea but if you don't really know your way around electrical then I would suggest not trying it. The risk is pretty high that you blow something. Alpine does sell the add-on negative trigger box.
