    Got it "done" and started it up.

    Voltage at idle on the dic is 14.6.

    Car sounded like crap until the lifters pumped up.

    Here is what it looks like with the redundant alternator wiring to the battery.

    There is enough thread on the bolt to accommodate the terminal so I lucked out on that.

    Getting close to the "finish" line with this part of the project (this car is a project).

    Had to order o2 extensions for the rear o2's as the new cats are further back.

    The car does pass sniff test and the #'s are in the mud. WHOO HOO!

    The unexpected plus was that they tucked the cats up higher so they don't hit the speed bumps.

    I'm surprised you didn't cut/solder extension wires on the existing O2 sensors. I did that on mine and used used Raychem heatshrink on the splices and wrapped it with high temp flex loom.

    Not familiar with your battery and can't clearly see how your wires are connected in the pics. When you say there was enough thread on the terminal, where are you connecting it? I say this because they make battery terminals that accommodate additional ring terminals such as the one from Racetronix - GMBT-B

    I would rather buy extensions then fart around extending existing wiring.

    As for the terminals, the ones you show (actually any) would push the battery terminal out to far for my liking.

    The battery side terminals stick out over an inch as they are also posts.

    I already killed the battery a few times sitting in the car zoning out on a few dozen tunes or a movie, so I may opt for a bigger battery.

    Update:

    Rear O2 extensions are in, but need to be secured.

    Changed the oil & filter while I was underneath the car.

    I guess I will take it off the blocks this week.

    Had success running the OEM radio/nav through the 5.1 system.

    Waiting for parts to finish that.

    Next project on this will probably be fuel system related, delivery and pressure monitoring.

    UPDATE:

    Grabbed the audio feed to the BOSE amplifier and found they are differential.

    Breadboarded a chip and it converts the differential signal to single ended and it sounds GREAT.

    The big problem is now volume control as the OEM radio controls volume via class II to the Bose amp.

    What a funky way to do things.

    Good info on the smaller alternator pulley. Any idea what size it is?

    Nice car!

    Thanks!

    I like it, the V is a hoot.

    After a long conversation with MECHMAN, the smaller pulley really helps in traffic.

    I found a Gatorback that was smaller with no problem, so the belt wasn't an issue, but also wasn't cheap.

    I think the pulley is about 3/8" - 1/2" smaller OD.
