Does any one know what wire would provide 12v when the ignition switch is on. For an obd1 p30. The fuel pump wire A7 dose not pvovide that. Any suggestion?

 

Cigarette lighter power

 

if you look in your fuse box, you will see 3 male spade terminals in a row. they are "accessory" power. one is all time hot, one is ignition switched, and one is light switched. test them.

 

cool thanks for the help. I should have been more specific. I was looking for a switch 12v right at my ecu. It was for my plx wb. They actully have a pinout chart on there website for honda ecu's that tells you what each wire is.
