Morimoto H8/H9/H11 HD Relay Harness (Low Beam)

An HID retrofit I had done on our Crosstrek seven years ago was beginning to malfunction and finally the lights went out. Found harness connection was corroded and the fuse was blown (surely related.)I needed to get the car back on the road ASAP for my wife, who drives at night frequently. The harness arrived fast and problem solved. Really, it was my fault, as the harness was dangling low and surely exposed to the elements - in Wisconsin, no less. I repositioned it, and used self-fusing flexible tape to wrap up all the connections.

Purchased the harness to use on a 2004 BMW 325ci with aftermarket HID headlights. The product came in when expected and seemed to be better made than some of the other relay harnesses I have installed in previous vehicles. On my specific application, the length of wire would have been adequate if routing over the radiator/shroud to each of the headlights. But for a cleaner look I decided to splice and extend each of the connections to the headlights, and the remote wire as well. In doing so, I was able to route the wiring behind the engine and tuck it with the original harness for a fairly seamless install.Overall good product that I have had no issues with. Won't take a star down because of the length of harness. After all, it is a universal product. Seemed well made too.

I really liked this harness and highly recommend it. The build quality is excellent! I unfortunately, had to return it because it would not work for my application.This harness has a single input from your existing car wiring to activate both HID ballasts. My car has a canbus system and I have individual ballasts installed for each headlight, so by only hooking up 1 input I will have dashboard errors with the system thinking one of the headlights is out. I had to return in favor of buying a unit that uses two inputs and has 2 outputs.

Best quality harness system I've seem yet. Works 100% as expected. Only problem I had was the size of the ring terminal was too small. Had to clip that and crimp on a 90° spade terminal with a quick tap for my side post battery.

Update: the replacement had an h11 adapter that was missing in thr first one. This is waterproof vs cheaper brands. I had to upgrade to this 5 years ago for my truck after a cheap one had corrosion from water at the junctions. I got another one fory SUV recently.Original:They sent me an h10/9006 harness. It is very similar to an h11 even the plug from the OEM h11 to this fits, but the OEM h11 pins inside the plug are narrower. It will fit together when you install it but the pins don't match up so it's installed but not working. 2 hours down the drain. Went to turn it on and found the issue. Not what I ordered!

Gets the job done. The wires are extra long. Feels great and high quality. It's a little expensive but honestly, this is the 3rd relay I've purchased because the previous went bad. If this outlasts 3 cheap relays, it'll pay for itself.

It didn’t fit my car even though it said it would

I will update when I receive my replacement. The harness package was open and the 25 amp fuse was replaced with a 20 amp.It appears that I was charged for a new harness, when I received one that was returned and the fuse was tampered with. The reason I bought this harness is to replace an existing Morimoto Harness that the fuse holder corroded and melted. ( After 2 years) These harnesses are 3X the price of cheap ones but evidently only slightly better in qualityUpdate. The new harness was unopened and had the correct 25A fuse. I installed it and everything works fine. I used dielectric grease on the fuse holder to hopefully prevent it or delay it from corroding and melting again.

Morimoto quality, enough said. Worked perfect.
