I ended up ditching the idea of putting them in the housings. So they are just bolted into the fog space. Work great and the empty space doesn’t bother me like I thought it might.
yes I wasted a ton of time grinding. I can't say if they are getting hot since I haven't checked them. I'm not 100% certain of how the module works, but it makes sense to me that they only see current when the turn signals are activated, so heat won't really be an issue in the module. Also some...
I did the resistors on the relay. I tried grinding the shunt down, couldn't make it work. so replaced shunt with 2 resistors in parallel. smallest ones I had were 1ohm so it needed two.
Lost my login info when I cleared my browser history and didn't set up 2FA. Anyways, the mini cats worked for about a few weeks, enough for me to pass emissions, but 420/430 came back.
I found this: Toyota-4Runner.org -...
Grinding the shunt didn't do anything for me and its nearly broken. Just tried a 1Ohm resistor, lowest I had in the pack. Got a single blink haha. I guess ill do 2 1Ohm in parallel and try again.
