ID for couple items>>>

[ZR1Vette]

In the amidst of my winter projects and while having the left wheel well rear housing removed these two items are attached to the inside of the housing.. one is a plug with a cover and the other looks to be a module of some sort.. any one ID what they are?

I believe the one toward the front (left in the picture) is the Vacuum pump fuse and holder. I haven't figured out the other one. Anyone? Anyone? Bueller?

I'm not 100% sure on the larger rectangle like box, but I do think that on our 90 Z's it's one of the "Quad Driver" boxes for the fuel injectors.

There are two of those, one for the 1* and one for the 2* injectors. Oh, I do believe that they are NLA, so be nice to them!

Tom...bingo...once you suggested the ID I went to the shop manaul and right on (item in pic is what is #1 in this graphic)>>

Also for the quick of eye... the VIN is stamped on the frame rail in the right of the picture...another way to verify car authenticity.

And rebelz gets the kudos for the ID of the In-Line Vacuum Pump Fuse 10 amp...finally found it in the Electrical Diagnosis Service Manual Supplement>

Just FYI, I believe they are actually both for the secondary injectors. Each one controls four injectors.

Yes, my bad....it's been so long since I looked in that section of the FSM. I remember doing all that looking in prep for me doing my 1st plenum pull. I was looking at everything associated with the FI system. noooobies!
I was sooo apprehensive when my 1*'s quit!

Ya I know so what was I doing down there...finding a suitable place for my hood light shut off switch.
