Hey fam... I’m having a little bit of trouble. I got my new bumper and it has wires for the fogs and I’m trying to understand how to connect once I remove the original number from my is250. If anyone can help it would be greatly appreciated. This is the brand.

 

Each fog fulb has a red wire and a black wire. So 4 red wires and 4 black wires (+ -) altogether each side. You might have to get a connector to form a single strand red wire and a single strand black wire then splice the factory fog harness and connect the wires. Repeat for the opposite side.
This is my thinking but I have not done it. I'm concerned with the load this would put on the wire and if the bulbs are sufficient enough to handle the output. Hopefully some others will chime in here.

Other cars I've just had 2 wires each fog side and then spliced the factory fog wiring and connected them.

 

Ok so here’s my question.... the fog lights have 4 of these one for bulb. So should I gather up the four negatives and four positives and crimp them to the prospective side of the oem lights after I cut and splice the original connectors

 

Nobody knows what to do?

 

If you want these to functions as fog lights then it's pretty simple. You can connect the leds to each fog light harness by splicing the oem harness or you can connect all four (two negatives and two postives together) and then just splice and connect them into one of the fog light harnesses instead of connecting them using both harness. It's pretty simple.
