    big 3 upgrade questions

    alright so im in the process of upgrading the bg 3, and i had a couple questions. First, when it says you can use any unessential bolt for the engine block ground, does that mean i could use a bolt that bolts on my headers? its like right there in the open so id like to use it if i can, if not can someone tell me where i should wire that wire. i have a 2005 ford explorer that the install is going on, 4.0 V6 motor. if anyone on here has done the big three upgrade on this particular vehicle, can you posts pics of your install your just tell me where you mounted/wired your install, thanks

    Yopu should have empty threaded holes on your block.. If so just find a bolt that fits one.. It might get a bit warm around headers dont you think?

    Yeah I'd rather not bolt it to the exhaust because of heat issues. Unbolt a bracket or something thats connected to the block and use it.

    yeah 9 times out of ten you already have an engine block to ground wire, just use the same one. if not, you should be able to find a bolt thats not a hassle to use. like alternator/starter bolt etc. some cars even have an existing grounding strap you can replace with your larger wire.
