boost gauge just tap into a vaccuum source. i used the line between fuel pressure regulator and throttle body, put a "T" in that line and run the line to the gauge. i can post pics if you need me to

the trans sensors don't need to be hooked up for the car to run, but it does make everything look nice if they're hooked up.

When I do an SR swap, I mount the ignitor on the passenger side, minus the bracket. There is a hole on the passenger side strut tower that has is threaded. Normally the ASCD equipment goes there, but you can use the top hole for the ignitor, and then drill a hole for the bottome one.

For the boost gauge, I tap the vac line that runs to my boost actuator.

The oil pressure gauge should have a sending unit. That unit screws into the location for the oil pressure sending switch (located right next to the oil filter). You'll need to pull the big long brace that anchors the intake manifold to the block. It blocks access to the sender. Some gauges send a sandwich adapter that allows both the stock unit and the gauge sender to simultaneously be used.

Here's a shot of my engine layout.

Just get a sandwich adapter or oil relocation kit in order to use the oil pressure gauge because later on you can add an oil temp gauge with the same adapter.

Igniter chip, run the engine harness on the passenger side of the car, extend the MAFS wiring, PS wiring, O2 if needed, and AC wire if needed.

Car runs fine without transmission harness connectors, though if you dont hook up the speed sensor you will not have a speedo.

As for IC piping I cant remember how many pieces you have but I think its two pipes or something. The longer one runs from the passenger side of the IC to the throttle body, should have a hole on it for a IACV or recirc valve. The shorter one goes on the driver side of the car, need to supply your own hot pipe from the turbo to this piece usually.
