Are there diodes across the relay coils?

Yes, there are two 8 channel Darlington array ULN2803 chips that contain them. They are also isolated via opto-isolators. You won't see any Back EMF transients with this board. They work fantastic and are very easy to implement.

No they do not. They have about 12 inches of wiring pig tail extending from the housing. The amperage draw is very minimal (watts divided by volts equals amps) so 42w/12v=3.5 amps this means you can hook them directly to a switch no relay kit is needed.

Nope, for my 07 Accord it required additional relay/wiring ($50). Love this unit though.

Yes, a simple crossover that is attached to the wire terminal input plate on the inside. http://youtu.be/w8Doa4-Tou0

Nope. That was actually in my review. I thought the price was right WITH relays but what you get is an empty holder. Not good.

none we could find. just kept blowing circuit breaker. had to go to circuit box and reset it there

yes, it is a straight through system. Have measured it with an OHM meter. So what goes in is what comes out. The fuse is just to prevent overcurrent.

Hello, they usually come with the wiring kit, and yes includes relay harness

The fuse holder is there. It slides out the front from between the switch and socket.

Update - I just opened the little box and the relay contacts are soldered to the small circuit board, you would have to desolder the relay contacts to find out if the supply can be separated from the output of relay. I guess it's probably not worth all the trouble.

They do NOT come with a relay. You can order the wiring kit.. For my application, I split up lights and put 2 each on an ATV & UTV without using any relay.. they are working fine.

I didn't run a relay. Just a wire from battery to the hot side of a switch with an inline fuse. Then from the switch to one red wire on a light. Then wired lights together. Then ran another wire for ground and connected it to both black wires. Super easy to install. Great lights.

Yes. I have the relays without the harness. You would have to wire the relay yourself.

Not to my knowledge. That was one ofmy complaints with the product. I went to Radio Shack and bought some additional wire and connectors. Problem solved.

The wires are not provided, but they provide the relay. You'll need to purchase wires and figure out where/how to route wires.

Yes, It comes with everything except relays. I purchased two of them and they are nicely made. Great product.

I would recheck the connections, and then the relay. You could swap the other relay if it's working properly.
