I don't have a picture but it is very easy. Do a search there must be 100 threads on this. Search on "throttle body bypass".

Yep, easy....
There's a short 5/8" heater hose going from the intake manifold up to the base of the throttle body. From there, it exits out the passenger side to the heater core.
Bypass requires you to run hose directly from the (front of the) intake to the heater core. The abandoned TB ports do not need to be capped.
OTOH, unless you take off the TB, remove the housing underneath and cutoff the abandoned hose nipples (to clean up appearance), I don't see the point.

Yes it does! To get it even prettier, spit on it and rub HARD!

It is suppose to keep the plenum and TB cooler, which keeps the fuel cooler, which make it burn more efficently. But the biggest thing is it makes the motor easier to work on when you don't have to drain the radiator down to work on the top end ...

So it doesn't look like it is cobbled together:
NAPA part number 9814
5/8" 90 degree hose
64" long
$22.78
No Tees, connectors, other bs required, just add 2 hose clamps and you are good to go.
