I just got some PIAA 1100X Mulit-Fit lights and I am trying to wire them into my bright light...does anyone know an easy way to do this? The wiring looks simple enough if I could just find the bright light wire.
I only have a diagram for the 650. It's easy enough to check with a voltmeter or even a test light. The ground wire is black with a white stripe. Pull off a headlight socket, turn on the high beam and check which wire provides voltage between it and ground. I'd recommend installing a relay off that wire so you won't be using it to power the headlights and running lights. The wire is barely adequate to provide power for the headlights alone. http://www.fordmuscle.com/archives/2...ting/index.php shows a couple of possibilities with the Bosch relay being a normal situation.
First, the hi-beam wire is the yellow one in the service manual I have for the 1000. It is probably the same for the 650.
A relay is a good idea or you may have trouble. If you want the hi-beam to switch the PIAAs on, just tap into the hi-beam line to switch the relay. A properly sized relay won't use very much power. A dedicated fuse where the power wire leaves the battery would be good too.
I would also recommend a battery voltage gauge if you run other stuff like grip heaters or a vest.
One of the better sources I have found for electric gear: www.Delcity.net
They are cheap, have decent stuff, and quick shipping.
Last thing: I have a set of PIAAs, and they have a warning that the bulbs won't last as long if they are switched on and off a lot. You may want to look for the same warning for yours and adjust your wiring plan?
