20V Blacktop Project - Days 24-25
More little things!!!
Coolant system complete: Heater hoses ran, water neck mounted to firewall,
new cheap overflow tank mounted between driver's strut tower and the rear
trunk, and tons of hose clamps.
Air/Fuel Ratio Gauge mounted and OX signal ran up to the front via shielded
single core instrument cable. I tapped into the cruise control connecter
under the steering wheel for ignition power & ground. Those 2 driver's
side vents are the perfect size for 2-1/16" gauges:
Battery mounted in the front trunk. I took the huge Summit battery box,
and basically cut it in half and moved the ends together for the small Trueno
battery. The strap to hold the lid down was used to hold the sides of the
box together. I used 1/4" threaded rod, some nylon lock nuts &
fender washers for holding the battery down. I got lucky when drilling for
the threaded rod. The nuts don't protrude under the car, instead are protected
by that supporting north-south piece (it's the jacking point for the front
of the car). Then made a bracket out of some aluminum stock, using my new
rivet gun and JB Weld to hold it together. While everything was out I also
cleaned up the mess past brake fluid spillage had caused to the floorboard.
Painted with Krylon of course.
Past few days I have looked all over for the throttle cable bracket, but
no luck finding it. That p*ssed me off. So I made one from scratch:
Extended the throttle cable, so that it doesn't drape over the engine,
using the original MR2 cable and the 20V cable. This was fun. It was actually
pretty easy, just took a while getting the right tools for the job. Here's
- Cut the ends of each off with pliers, being careful not to cut the actual
- Strip the protective rubber about 1/2" back exposing the metal structure
of the cable housing.
- Measure/mark the length of cable needed for when your foot is off the
gas pedal & when it's all the way down. Do the same on the extension
end, this time using the actual throttle assembly. If you need to expose
more cable on either side, cut off more of the housing.
- Once you get the lengths right, using a 1/16" ferrule (you may need
to enlarge the hole to allow both cables to fit), crimp the 2 cables together.
- Using some 5/16" ID fuel hose I had sitting around, that acts as
a protective covering for the exposed cable/ferrule. Make sure the crimped
ferrule can slide through it easy enough.
- Use some heat shrink tubing on the ends of the joint to keep moisture
& dirt out.
- Then some clamps to hold the hose onto the metal housing
