My thoughts would be twilight sentinel but the box looks a little different. Did you download the service manual and see if it’s in any of the under dash schematics?

I think the black box I was asking about is the cruise control module, I found a connector tucked way up in there that plugs into it....if it helps anyone else :)

New question, in front of the driver's side valve cover, bundle of wires. There are 2 white ones that Mark tied into and ran one into cabin for a gauge I assume....what would those white wires feed a signal for?

tach on the dash.  They will also feed an aftermarket tach.

There is another single wire that is the fuel pump test wire.  Put power to it and the fuel pump will run full time

Thanks! Must be for a tach, he has the 2 whites connected into one going into cabin. Picked up a battery today and plan on starting to test as much stuff as I can before the dreaded first start. Also, wanting to avoid as many potential problems as I can I'm going to swap known good parts out of my car for first start, like computer, maf, coil pack.

the white wires are actually one wire with a connector on it to be able to plug into a test tach...sure looks like two wires the way it is connected.

Think that is a good idea to use the good stuff to eliminate that problem.  Be sure the crank sensor is clearanced right.

Endo scope came in so checked each cylinder, all look great!! Got motor turned to TDC on cylinder one and was going to set the cam sensor tonight but when I prime the motor would just have to reset it. Also that IAC 45 degree bracket puts that thing right in the way...pain in the ass! Probably eliminating that prick, dont use a large up pipe so no need to keep fighting it.

I have one on my GN.  I don't recall it being a problem but that does not mean anything these days LOL

Did you find a substitute for the tv cable?

Not yet, LONG way from actually driving it so I'm holding out hope that highway stars gets some in before I need one!

It's a combo of access problems above the cam sensor, there's a fuel pressure gauge on the end of the rail, that IAC issue, and all the wires running thru there are all in that plastic wire protector so it's a cluster

for sure a cluster.  It's hard to see anything there with or without that angle adapter.  I have a four inch pipe on the Gn.  I have another adapter that has been laying in a drawer for many years that I never installed on the T.  I think about it now and then but you have convinced me to let it lay in the drawer

The fuel pressure gauge on the end of the rail is in the way on yours. Here's the angle adaptor on mine and the fuel connector on the end for the in car fuel pressure gauge...and I ran the 4 inch intake with zero clearance issues.

You'll prolly have to remove the angle adaptor on yours to make it work.

New question, found this plug under the coil module, what should it plug into, can't find anything in this area not used
