I used the Autometer pod on my A-pillar, which leaves something to be desired. The fit of the pod to the pillar is not perfect, but once installed, it looks OK, If I were to do it again, I would remove the cloth from the A-pillar, and section off the pods and make them integrated into the A-pillar plastic and then recover it. However if I was going to spend that much effort, I'd build a new dash cluster the way I wanted it.
The pod mounts to the A-pillar with 4 snap in posts. Double stick tape is not an option, so suck it up and drill the holes. I also drilled a 1/2" hole for the wiring.
The gauges themselves went in pretty simply. They are a friction fit in the pod openings.
At this point I started to use the 1/8" hard nylon tubing for the gauge. The 6'of nylon hard line that Autometer provided wasn't enough to reach to the gauge by itself. Between the firewalls I routed the tubing behind the master cylinder and into the ECU box thru a grommet already there.
From the ECU box into the interior was a frustrating trip using a claw type pickup tool and a lot of wiggling & cursing..
I picked up the tubing in the interior with the claw thru the fuse panel cover and routed it up thru the hole in the A-pillar and into the boost gauge.
A little dab of teflon permatex sealant on the threads of the brass fittings, and I snugged up the adapter to the gauge. I slipped the nut over the line, then the brass crush ferrule. I inserted the tubing & ferrule into the adapter on the gauge and snugged it down with the appropriate wrench.
Oil pressure: The sender goes into the oil cooler adapter on the side of the engine. The Autometer sender is 1/8" NPT, which sort of screws into 10x1 metric hole on the cooler adapter, but not really. I was able to locate an 10mmx1 to 1/8" NPT adapter, so I used it. This went into a T-fitting, which I detail on its own Installation Page.
I ran the wire from the sender thru much the same route as the tubing earlier.
I haven't had any problems with the needle bouncing from the frequency valve for the turbo. I didn't use an accumulator or the like. I did not notice any boost spikes over 1 bar. Perhaps with 100+ air temperatures I won't...
Anyone who wants to do it I suggest having the parts and tools on hand when you start, or else plan on taking the whole weekend to do it.
