Hey guys,
I am putting in the 3 Bar map, and was wondering which wires go where. I know what the wires on the GM map are for. Just not sure which one splices into which of the stock wires. Can anyone help me here? Its in a 93 lude if that matters...
THanks,
Josh

Enjoy.

 

Hey,
I wish it were that easy The prelude seems to be different...I have a white/blu, blu/wht, and red/black wire...
Thanks tho
Josh

 

well, one is ground, one is 5v and the other is the output to the ECU, right? So, turn on the car and use a multi-meter to figure out which are the 5v and ground by making a circuit between them and the third is the signal to the ECU. I assume the red/black is ground, but me no know ludes...

 

Just grab your manual and fugure out which wires are the 5v, GND, and signal wires. Stubstitute those in for the ones in the Hondata install. A multimeter will tell you which are which. Keep the sensor connected with the key at the ON position. Take on lead to a wire at the back of connector(you may have to force it past the little rubber seal) and one to the engine block for ground.

The 5v wire will be 5v of course, the signal wire should be somewhere around 1v, and the ground wire will be 0v I think.

 

Hey,
Thanks guys...don know why I didn't hink of that ...hehe.
Tuning tomorrow
Thanks again,
Josh

 

interesting...one is at 4.69...another 5.01...and then ground is .011...normal for signal wire to be up around 4.7?
Thanks,
Josh

 

use a test light for finding sources of power and ground

 

I thought that I had it in right, but when I tart the car it starts right up normally, but then just dies. Did it do this for anyone else?
Thanks,
josh
