The failed diode missing its connection to the orange. This is about 6-8 inches from the h13 connector.

The new morimoto has no splices and uses a mesh type wire organizer instead of the corrugated plastic tubing. Also one other difference, the grounds are located at the projector lead ends (2x) instead of (1x) long batt- lead. This means you have to back out some fender bolts.

I know what you mean, right about now is the wet and dirty season of winter in Minnesota so I got an unlimited car wash pass from a Holiday gas station near my house. Since I got it I think I have washed my car every day, sometimes twice a day (under body soak included). My DDM fog light ballasts are zip tied to my lower radiator support and I don't have the plastic piece (splash guard) on the bottom of the bumper. They have just been getting pounded by water every wash and have been holding up pretty well for how cheap they are.

gtferrari I had everything plugged into the driver side as there is the most empty space down in the bumper but i think that is where i went wrong. Theres nothing to block the road slush or other wetness coming off the tires. Atleast on the passenger side theres the washer fluid and coolant tank. This winter i was springing for a lot of under body washes and i bet tgats how the water got into the harness

popwarhomie First I've heard of problems with TRS other than user error.

TRS is great.

gtferrari The factory harness is well made. I dont know how water got into it. One tiny diode rusted and failed. I never lost my lights just the ability to have high beams. I had an issue emailed them after hours and had an answer first thing the following day. You can call them and talk to somebody if you want too. They are very polite and dont talk down to you. Ordered the replacement harness last night and it shipped this morning.

DarderSauce Every time I hear about people having any sort of issue with their HID's from TRFS I get nervous about doing a retrofit. That is until someone says they fixed the issue with the older equipment.

gtferrari with the condition of the wires i will just replace the harness instead of trying to clean everything up, finding a new diode and resoldering it in.

now they have a module that replaces the pair of relays. makes me wonder if they were having problems with the old set up. they did go from 80amp relays with green leds to 40amp relays with red and now have replaced them all with a nice looking morimoto black box that matches the look of the ballasts

for $35 why not?

Thanks for your email and patience waiting on a response here. I'm sorry to hear of the issues with your harness recently.

There is a diode installed from the high-beam to the low-beams that keeps the ballasts on when you select high-beam, so that was likely either burnt out or removed somehow.

If you prefer wire in a diode, it's a 1N5404 that goes with the stripe facing the low-beam wire coming from the relays

popwarhomie Both my retrofits with all TRS parts and going great. 2 years on truck and 1 year on car.

A7xschecter6661 I didn't really read, I am tired and just skimmed. If you hit the high beams and the lights cut out completely, you have the same problem I had.

It was the relay box on the nice wiring kit they give you.

It's a gold relay box shown towards the bottom of the page. The first one I got didn't work for high beams and I messed around with everything trying to figure it out. Called them and they sent me a new one for free.

Been good for months ever since!
