Iam posting it here cause its related to the 5th gen electrical system.

I just retroed my friend's 97 Accord with E46 projectors,ballasts and bulbs but having a problem. I also bought dedicated harness with relays so we dont have to worry about messing the electrical system.
The problem is when we plug in the HID kit it doesnt light up neither through the harness or even when plugged in directly to the vehicle's connector. It lights up fine when directly powered through the battery but not through the headlight switch.
Iam guessing that the vehicle's relay cannot hold enough power and it trips when we plug in the HID but it works fine when I put a regular 9006 bulb

Any help would be appreciated.

not sure if you did, but does the relay power up the 9006 bulbs?

im thinking its an issue with the harness..

sometimes the headlight plugs are wired opposite what the ballasts input is. Since halogen headlight bulbs have no polarity, whoever assembled the harness just put the wires in without worrying about polarity.

Check the vehicle headlight connectors, find which is the power and which is the ground. Also keep in mind that the accord has ground switched headlights... meaning there is always power at the lights, the ground leads are switched on and off... so if you connect a relay to the power side of one headlight plug and the other side of the relay coil to ground, the relay will be on all the time.

:thinking: i dont think so

but yeah... the polarity may be wrong.

We even tried a new battery but didnt help. I will try to reverse the polarity to see if it works. Thanks for the help guys

^^ thanks for the advice, it works fine now. It was the polarity.
