Unknown branch on wiring harness
I am in the final stages of preparing to reinstall the engine after installing studs for the heads and have found a branch of the wiring harness that has no plug and 4 exposed wires. I am sure that this didn't happen during removal and disassembly and there are no corresponding plugs with exposed wires attached to anything near the harness.
From the attached pictures does anyone have an idea where it goes and to what it should be attached?

Re: Unknown branch on wiring harness
It plugs into the switch at base of shifter, its at top on tranny middle rear area real pita to get too.... (neutral safety/gear selector switch) I hate that connector I had a pin burnt in it
Oh and double check ground wires, if same as 96, 1 ground at/near rear head that a engine/tranny mount bolts too is for o2 sensors... and my personnel most hated but easy to get to ground right side lower block under same head near the speed sensor on tranny. its the PCM ground. car will start drive a few miles LOL and die and not restart run a self on board test it comes up as NO PCM that a dead give away if its off or broken..... yup hate that one..
