aiight, here is a valid question.

When doing modifications/service to a 420a, i run into a lot of sensors

what is the proper way to take em off or disconnect the clip part without bustin the clip. ive done the zip-tie mod a few times, and want to get it right from now on.

TAKE YOUR TIME! The red safety clip in like your ignition coil clip slides left and right. A fine pair of needle nose pliers or screwdriver can push it out. Other sensors have a clip that is "latching type". If in doubt, push up a little on the little latch(like O2 sensors) and wiggle back and forth while pulling. Theres no real certified way of undoing clips except to not break them. If you still feel a little aprehensive, GIVE HER HELL and practice your soldering!

Most of them are easy - pull. if it doesn't come off, pull harder. if it still doesn't come off, look for a clip on the connector. Lift it a little bit with the tip of your finger while pulling. If it STILL doesn't come off, lift a little bit more while pulling. if it STILL WON"T COME OFF, give up, grab a screwdriver or a 10mm socket because it's screwed in. I've never run into a sensor that was incredibly difficult to disconnect (except the oil pressure sensor on Joe's car at 2am, when we started at 1pm the day before) so generally it's an easy deal.

In a nutshell, it goes like this: Don't worry about. The only sensors that are really hard to remove a buried deep in your engine bay. if you can reach it to disconnect it, you've removed so much stuff already that you'd damn well better be able to unplug that sensor, or you're in way over your head.
