Question for the metal fab guys
 

I want to install a 7 pole trailer connector on my blazer
Would like to mount the connector threw the bumper just not sure what type of hole saw blade to use
Is a decent bi metal blade going to do it ?

Make sure you clear the wires behind there while drilling. Hole saw works great.

ya home depot got some good hole saws.

personally i use the cheap harbor freight set.

yep ,thats pretty much it
the connector I got has the 4 wire and 7 in the same unit ,not a fan of seeing the wiring hanging all the time
was thinking of right of the plate , mine is a 2dr so no tire under the back any how using the existing hole

Multi-Tow® 4 Wire Flat to 7 RV Blade & 4 Wire Flat

Thread jack where is the connector located. My RPO says i have one but havnt seen it. Unjack

Should be a bundled wire with tie strap taped up on the end

mine has a existing wire bundle right behind the bumper and it even seems to have a heavy (12ga) wire included in that bundle and a 4 wire flat connector
I only plan on grabbing tail and signal power there , going all new for brake controller to the engine compartment
