Gauges galore! I got a single and a double universal A-Pillar gauge pods from Summit Racing for less than $10 and Bosch electrical oil temp and pressure gauges for under $20 and a Sunpro (Bosch) boost gauge for $3!!!
The universal pillar pods required some molding with a heat gun to get them flush with the factory A-pillar trim. The gauge wiring was straightforward and I mounted the oil temp and pressure senders to the TRD sensor plate which mounts right under the oil filter. I used an Add-a-fuse for gauge power and lighting and routed the ground wire for the gauge lights to the black wire on the dimmer dial so that they dim with the dash lights.
I'm pretty happy with how they came out, even though it's not as clean a a custom pillar pod, you can barely tell the difference, plus i'll sleep better knowing I saved about $100 on a piece of plastic.
One last thing, it would seem that the TRD sensor plate is not a great place for the oil pressure sender since it sits high above the engine. Once the oil warms up, the gauge reads 0 at idle and low rpms so I'm assuming the pressure drop is too great for the sender to get an accurate reading, which is a shame since it looked so clean tucked away behind the AC compressor. I'm planning to relocate the pressure sender to the port on the engine block.
