I've tried to document some of the modifications I've made to my truck.
They've all be done with the direction of the various helpful people on
the TDR forums.
Gauge Pod Cluster - This replaces the
driver's side A-pillar plastic cover with a new one with 3 shaped holes
for gauges. This had to be done first, otherwise I wouldn't have
anywhere to put my gauges.
Boost Gauge - This deals with running a
vaccuum tube from the engine block up into the cab to the boost gauge.
Exhaust Temperature Gauge -
By far the most nerve-wracking for me; it requires you to drill a hole
into a perfectly good down-pipe.
Fuel Pressure Gauge - While simple
to explain, these senders caused me, by far, the most trouble. In fact,
I ended up totally replacing the senders with a different type by the
time I was done.
