I decided that I wanted to rotate the Holley Lo-Ram front to back, which will put the MAP sensors in the front.



The main purpose for rotating the manifold is to clean up the area behind the intake and have the ability to use the stock oil pressure sensor in the stock location. I should have done this at the beginning...



Rotating the manifold involved a bunch of changes. One of them being the plate that holds the boost solenoids. It still fits, but it had to be cut to clear the Bosch TMAP sensor.



I also picked up some AC hose ends locally. The top hose that goes to the condenser is from the compressor.



The lower hose goes to the dryer. I have a new dryer on the way along with a AC pressure sensor, which will replace the binary switch. The AC compressor will be controlled by the Dominator ECU and the HardWire PDM.



I got a 45 degree fitting for the #10 hose that goes from the evaporator to the front port on the compressor. The rear port on the compressor is a #8, and goes to the top of the condenser.



I also took out the dash insert.



With the ash insert out, I will be able to get to all of the wiring and ducting behind the dash, without actually having to pull the dash out. The 3 gauges that are front and center will be the Holley CAN RPM and Speedo, as well as a small fuel level gauge.

The holes on the right will be filled in. The 6.86" Holley Pro-dash will go where the three larger gauges used to be and below that will be two AC vents.
