Installed new LED DRL's, new LED signal bulbs (front and back), and LED reverse lights. Now suffering from Hyperflash so installing the Novita LM487 flasher relay once I find my 8mm socket this afternoon.
Update on flasher. Did it seem to work?

while waxing, i notice the pass side floor was wet so i pulled off the sill and the carpet and padding was soaked, so i put a towel between em and stood on it a few times to help dry it up, then stuffed some crap under the rug to lift it up so it can dry , is there a common thing that leaks down there? i pulled the a pillar trim, theres no water trail, and the head liner is dry. thinking it might be the xm antenna i suppose, if thats the pass side box on the roof.

and its not coolant, it just water, sill to about 1/2 way to the console was wet.

No problem, let it dry out and if the weatherstripping looks ok to a garden hose on a warm day and spray the door and see if that causes anything if that doesn’t cause it make sure the cowl drain on that side is clear

You gots a suns roofs?

Something about drains going down the a pillars and being clogged....supposed to drain behind the front wheel well liner....i think

i blew them out last month when a new stain showed up on the moon roof slider. then dumped a glass of water in the drain pan and i got water from both front fenders @ the door and behind the front doors. so pretty sure those are ok.

Yep, worked really well. Super simple to swap out. Although the 'tempo' doesn't sound like the original but it stopped Hyperflash immediately. I'll take a few photos tonight of all the LED upgrades.

Today I swapped out the third brake light as it half LED's had stopped working. I got the black housing / smoke lens version which I think looks much nicer with the black/grey look of my truck!

Would it cause an issue if you have resistors with that module?
