Innovative Products of America IPA Tools - Relay Bypass Switch Master Kit W/Amp Loop (9038A), One Size

Nice product to troubleshoot with. Easier then making up jumper wires, Wish it had a better stowage box, but I'll find something.

There are larger and more comprehensive relay circuit testing kits out there (like Lisle's 69300 Master Relay Test Jump Set or AESWave's uActivate Master Kit) but if you just need to bypass a relay and power a component at the fuse/relay box, this kit has everything you need for quick and easy circuit testing. I have used this kit many times in the shop since purchasing it to test fuel pumps, starters and other circuits where a relay is used for component control. Simply inserting this relay into the appropriate cavity in the fuse box and activating the switch can immediately give you a path to take for your troubleshooting process. Before it, I would just use a pre-wired inline fuse holder with spade terminals crimped to the ends of the wires, but this is simpler and ensures you have a good connection in the fuse box. I have encountered the odd situations where the design of the relay and/or the fuse box would not allow this to be used (the OE relay and cavity are a bit too small for it to fit) but it does not happen often and most times I can use this kit with no issues.

They are great works good

Cheaper that paying to fix the Def system

I use these daily
