This is the location I chose for my ECU placement. It makes
it Kind of a pain to get to, but it was the only logical place I found.
(sorry for the blurry pic!)
The Relay Box
I designed and built this relay box mainly for the whole
"start / run" cycle power issues. At first I was under the
impression that there wasn't a good power transition
The Relay Box
For the ECU Power. so I ran these relays to make sure that
the ecu was supplied with a solid 12-14 volts, and fused.
The engine compartment in work
I took some basic engine compartment pictures just to show how I ran the wiring.

Another pic of the engine compartment. (note: the placement
of an "impact" switch on the pass. side firewall.)
The engine compartment in work
This picture is to show the placement of an electric fuel
selector valve. I decided since I have dual tanks, I would like to be able
to switch from tank to tank with just a "toggle" of a switch.
The TBI Unit
The GM throttle body supplied from Howell Industries.

The Custom TBI Unit Spacer
This is a custom spacer ring that a good buddy of mine
created for me to still use my factory air cleaner. It sure is nice
knowing a machinist! Thanks Mike!!)

How the ring looks on the TBI unit. (Good work man!)
Fuel Pump Location
Here is a quick view of where I mounted my fuel pump for
the main tank. I chose this spot mainly because my exhaust runs too close
to the inner frame rail, and ease of maintenance. I will be installing the
aux pump later.

Here is the completed setup.
The Bare Manifold
This is a shot taken right after the Carburator had been
removed from the engine.
TBI on Engine
Well, Here is the first picture of the Throttle body
mounted to the engine.
Another View
I took this shot to show how the throttle linkage was
modified to fit the unit. We were able to also modify the transmission
kick-down linkage off the carb to work with the new TBI unit.
The Completed Setup
Ahh, Finally we get to see how it all came together. the
Spacer fits perfectly, and there is no interference with the hood! Now all
we need to do is fire it up!
A Quick Test
Here I am doing the "ditch test to see how the truck
idles at an incline. It worked great! (In the past with my Edelbrock the
truck would stall on this test.)
Another View
I also pulled right out, turned around and put it nose down
into the ditch. the truck ran perfectly. (sorry I didn't get a pic
of that though.)
A third View
A quick side shot of the test.
