1990 JEM 777 DY wiring

Hi guys

I took the pick guard off my 1990 777DY and noticed some strange wiring coming out the middle pickup - thin wires - leading into some white taped area - as seen in the pics.

I'm the second owner. It's never been modified. Is this how it should be?

Appreciate your input!

Looks like someone has tried earthing the pickup mounting screws. Maybe they were getting some earthing related buzzing and this is their fix?

Hey thanks for the reply

Sorry, I should have pointed out the wires running across the screen are just the strings from the guitar. Is that what you meant?

Nope, the other wire I see (besides the coil wiring) is a bare wire leading to the middle pickup screw/spring assembly. Is this the wire you were talking about?

Ah! I'd not even seen that before!

I was referring to the thin black and red wires coming out of the middle pickup that seem to disappear into that white tape. It just looks a bit gash!

That other wire though; no idea what that's about but well spotted!

It looks right to me, the thin wires came out from the pick-up and they are taped to the big cable just to maintain its direction, they are not soldered. Here it is my ‘87 SK middle pick-up wiring. I think it looks similar to yours, but the tape has failed over the years and the cables are free now:

Ah! Yours are the V1 (Vai 1) paf-pro pick-ups! Mine are unmarked (first run), then the V1 came out and finally the paf-pro DP151. Some say that the unmarked and V1 sound better than the DP151 and drool over them, but maybe it’s just mystic to it.

Hey thanks for the response. Iíve learned something new about the guitar tonight. Didnít realise there were variations on the pick up types. Thanks!

Any idea what that bare wire is running into the middle pick up? Quite hard to see it unless you zoom in.

Black wire to the 5-way switch, red to the volume pot.
