First off I am an electrical noob, and after read years worth of reply's on this subject, I have come to the conclusion I cannot wire something without a diagram, so I just made one of the AC switch in my car. I was told ground out goes to my ECU B5 and ground in goes to ground (which confuses me even more) Instead of someone trying to explain it to me, I am asking someone to just flat out tell me where wires 11,12 and 14 go, and if your billy badass could you tell me what those wires do also, it would be a life saver. THANK YOU



EDIT: I know I have to cut B5, I just dont know what wire I run from the AC switch to that wire and which one I just ground out.

I'm an electrical engineer, but I'm to tired right now to go over all those control blocks.

Go buy a cheap voltmeter from radioshack.

Before you cut the connection, measure the voltage at B5 with the AC switch on and off to make sure. When its on, B5 should be 5V or 12V. When the switch is off, it will either be 0V or close to it. Connect the + on the voltmeter to B5, and - on the voltmeter to a ground/GND pin on the ECU.

The logic could also be reversed. Either way, if the voltage is higher than 5V make sure the controller you connect it to can handle logic voltage.

I already have a voltmeter, and I know there is 12v at B5 already

 

Still dont have an answer.... here is a diagram of the switch I got of Hondata's site, if you ask them this question all you get is a do this do that but it never makes sense to me, I went through 25pages of nothing I could comprehend, maybe this will help a little....



Does this appear to be correct? I gather from this diagram that I find 12v at the switch, cut it and run it to B5 and then the other one just to ground and snip the 3rd one?
