Is it plug and play with the 4000 LED's?

Sorry Sean but I don’t know. I bought this to desire my old Bentley and never used it. I’ll sell you mine cheap.

Im looking for just the connection to the lights i dont need the rest of the harness?

Go on the Stedi lights website ... They have the exact small jumper harness you are looking for.

Will this work with the Rallye 1000 lights too?

H84994031 is the harness that will work for the Hella 1000 acording to the manual. Im not sure if this harness you are looking at will work but it apers like it would. they may be the same.

Suppose I want to run 3 Rallye 4000 lights. How would that work?

I purchased 2 wire kits to operate 3 - 100 H3 blubs in each fixture (This wire kit has the SPECIFIC connector that mounts to the Rallye Light). Then connected jumpers from the first relay to operate the second relay. Works like a dream and been doing this for over 10 years and had great results.
