LOTS of progress to report, as I've been on vacation the last several days.
Wiring harness installed, positive cable shortened and installed, radiator plumbed and wired, front end all wired up, BCM installed and all connectors plugged in. In the back I relocated the MAF sensor plug, identified/tagged a bunch of plugs that can be removed, positive cable connected to the starter, and everything laid out for the fusebox installation. Spent a bunch of time cleaning connection points and ensuring that ground points are clean, debris-free, no corrosion, etc., and ran continuity checks with a meter between the grounding points.
Dug the fusebox and ECU out of storage boxes, checked all the fuses visually, cleaned the box and storage tray ahead of installation. Verified all the coolant hoses are plumbed and the system is closed, checked/verified fuel pump installation and fuel line running to the injector rail. Next step is to install the fusebox and ECU tray and connect everything up, and install the battery. Then it will be time to fill the cooling system, change the oil/filter, add some gas and see if it will prime the fuel system and crank. I should verify that the spark plugs are good as this thing has been sitting for a few years.
A few questions come to mind that I haven't been able to find good answers for:
1. The shifter cables are run but the shifter itself isn't yet installed. What's a good way to get the (manual) transmission into neutral, or is this not a concern (car is on jack stands, rear suspension/brakes are done, but no hydraulics yet)?
2. I purchased the muffler from DF. What gasket do I need to purchase for it? I'd like to get the exhaust in place before I try to crank, as this is in my garage and I like my neighbors.
3. I found a few grounds in the wiring harness at the back of the car. Where are you all attaching your grounds back there?
As always, I appreciate the help from all of you. You've all given me confidence to keep pushing on this build, can't wait to see it running!
