I think you have the jist of it......

Thanks for the affirmation. I'm a little nervous with all the sophisticated electronics in the LC250, but there doesn't seem to be too much I can screw up with this mod.

...I hope!

No not really, be aware if you have the relay in the Disconnect mode and you try and start your LC, you are going to get all kinds of pretty lights show up on the dash......LOL not to worry tho' just put it in the connect mode and start normally, if the error message are still being displayed, just do a key cycle (shut down, then restart) and the error messages should go away. I've done it a few times and the message have away disappeared after a couple of key cycles.

Just FYI.. I installed the 41.22 wired kill switch. I tested it and was expecting a light show when trying to start the LC and the switch was off. To my surprise, nothing happened. No start, but no check engine lights either. I tried to go as 'stealth' mode as possible on the install (hid the 41.22 box in the engine bay) so a cursory look under the hood would not be obvious an aftermarket device was installed. I'm keeping the OEM (purple relay) in a safe spot in the LC in case the 41.22 decides to crap out then I won't get stranded.

When you drill the hole for the wire to exit, measure carefully from the top of the base to the height of where you soldered the new wire to and drill the hole just slightly bigger than the wire. It's a bugger to get the cover back on, but the intent is to keep it as weather proof as possible. It doesn't take much to corrode the contacts in that small relay. I would also highly recommend you place the OEM purple relay in one of the empty holes in the fuse box. That way should your mod ever fail, you can simply put the OEM relay back in and be on your way.......

Certainly wise advice to have the unmodified relay handy. Will do that for sure.

I had in mind to use a tiny amount of RTV silicone to seal any little gaps around the wire access hole. Assuming I don't go crazy and muck up the inner workings of the relay, is there any other reason not to do this?

Thanks for the advice, EOD!

It won't hurt anything but ...... If the hole is just slightly bigger the chances of intrusion are minimum and it is sitting inside the fuse box which further reduces the chances of intrusion. On my 1st one, I superglued the cover back on RTV'd the wire hole etc...... on the 2nd one the wire hole is very tight and the cover snapped back on so I'm confident it's as good as it'll get without all the mess of RTV etc... Now if you have to make the hole bigger to guide the wire through etc...... then yes I'd apply RTV.

You can use dielectric grease for things like this. I've used it to fill switches in wet environments. It promotes conductivity between contacts yet does not conduct electricity. I slather it on everything electrical; battery post, trailer connectors, extension cords, you name it.
