Chevrolet C10 Gets Wiring Upgrade - First Things Finished - Tech

This is the computer used to manage the Gearstar 4L60E transmission. The Gearstar computer is very light and only required sharing one mounting screw with the Power Bass mounting brackets.

To ensure no exhaust fumes or rainwater would be able to leak into the cab, the wiring was sealed up with a silicone sealant.

Notice how the Gearstar computer was pinned into the corner allowing it to be affixed with only screw.

Once all of the speaker wires were connected they were grouped in a Teflon lined sheath and routed to the Power Bass amplifier.

The best electrical tape money can buy to produce a super clean job is professional grade 3M Super 33+. A single-edge razor blade makes a clean cut without stretching the tape.

To prevent any chance of the bare positive terminal screws shorting-out on the Power Bass 1,600-watt amplifier speaker wire connections, we used 33+ to cover the leads.

The input and output RCA leads to the Power Bass amplifier are easily identified with red and white markings.

With the amplifier and speakers wired, the next operation was to locate an out of the way spot to mount the Painless auxiliary fuse block. It was determined the best spot was on the passenger side adjacent the glovebox.

Here's the face of the Painless fuse block. Notice there are circuits for an electric fuel pump, electric fan, and additional accessory items that are not present on a stock C10 fuse block.
