1990 tracker isc solenoid test?

[rjm]

you can barely see the brake booster in "engine bay 1" photo -its hidden by the air filter box. you can also see the clutch cable in the same photo (indicating it is a manual trans (5 spd) with power brakes.
my concern is the polygon hole shown here and the lack of hole shown here in gasket? I am using SMP kit # 1716
