Gauge Hookup and Lamp Wiring:
1. Drill a
⁷⁄₈
" hole in the firewall. Route
the capillary tube from the gauge through
the hole in the firewall to the engine. DO
NOT CRIMP the tubing closed during
routing. A rubber grommet is recom-
mended around the tubing where it passes
through the firewall.
2. Determine whether you will need the
supplied ½" adapter to connect the capil-
lary tube to the engine. (See Diagram D)
3. If you do not need any adapters, attach
the tubing to the engine using the ¼" self-
sealing nut. If you need the ½" adapter,
install it in the engine port. Then insert
the heat sensing bulb and sealing nut into
the ½" adapter and carefully tighten the
sealing nut. (See a VDO catalog if a dif-
ferent type of adapter is necessary.)
DO
NOT OVERTIGHTEN THE SEALING
NUT OR YOU WILL DAMAGE THE
TUBING!
4. Wire the light socket. (Diagram A)
At this point, installation is complete. Be-
fore starting the engine, re-check the rout-
ing of the tube from gauge to engine.
CAUTION:
MAKE SURE THE TUBE IS AB-
SOLUTELY FREE FROM MOV-
ING AND / OR HOT ENGINE
COMPONENTS, AND THAT IT
IS TOTALLY FREE OF KINKS.
Start the engine and turn on the lights to
make sure there are no leaks and that the
gauge illumination functions properly. If it
doesn't, recheck your connections and your
wiring. Check tubing connections for leaks.
