It takes about as long to describe as it does to do….
Simple Winshield Installation
1. Attach the SGII connector cable to your OBDII plug just in front of your right knee and behind the lower edge of the dash; it’s white.
2. Take off lower left fuse box cover for access.
3. Remove left A-pillar trim piece: Pop-off guitar-pick looking bolt covers on grab handle, remove two Torx-head screws / grab handle, then carefully pull cover away from A-pillar.
4. Use wire fish (coat hanger) to pull SGII cable through gap between the lower side of the steering column and A/C vent duct from above the accelerator pedal to the fuse box (line-of-sight opening).
5. Use wire fish to pull RJ45 / ethernet cable from fuse box area up to A-pillar opening (also line-of-sight).
6. Connect your SGII to the RJ45 plug and then position where you want it along the upper windshield just above your steering wheel with hook & loop fastener.
Note: The slight tint used on the stock windshields pretty well hides the SGII from outside view.
7. Tuck the RJ45 / Ethernet cable into the front edge of the headliner.
8. Tape or zip-tie the signal wire to the existing harness to keep it from rattling or chaffing.
9. Reinstall the A-pillar cover, put the fuse access panel cover back on, and your done.
Center / Overhead Console Installation:
Extra Parts Needed:
a. RJ45 (aka Ethernet) In-Line 'female/female' connector
b. 8’ - 10' RJ45 / Ethernet cable if you’re interested in running it to where it would be closer to the rear view mirror.
Note: You can use a shorter RJ45 / Ethernet cable as an extension but you’ll still need one that’s about 6’ long as the In-Line connector is fairly large and can’t be easily accommodated anywhere above the A-pillar.
1. Take off lower left fuse box cover for access.
2. Remove left A-pillar trim piece: Pop-off guitar-pick looking bolt covers on grab handle, remove two Torx-head screws / grab handle, then carefully pull cover away from A-pillar.
3. Use wire fish to pull your 8’ – 10’ RJ45 /Ethernet cable through gap between the lower side of the steering column and A/C vent duct from above the accelerator pedal to the fuse box (line-of-sight opening).
4. Use wire fish to pull RJ45 / ethernet cable from fuse box area up to A-pillar opening (also line-of-sight).
5. Remove the overhead center console: Remove 2 screws above the eye glass holder and then with a firm grip pull no more than 3" – 4” away from the headliner… there’s a wiring up there. Once loose, disconnect the wire harness feeding power to overhead lighting by pushing down on the small release tab and pulling the male and female connectors apart.
6. Remove blank panel from overhead console: Remove all 5 (maybe it's 7) self-taping torx head screws holding blank in place, remove blank, then reinstall one of the short screws to hold power sun-roof switch blanks in place.
7. Make simple V-shaped aluminum bracket with cut-out for RJ45 cable connector and attach to overhead console with double-stick tape. Attach ScanGuage II to aluminum bracket with Velcro.
Note: This may take some dry-fitting to get everything lined up the way you’d like and so that the overhead console fits back up flush to the headliner.
8. Route the RJ45 / ethernet cable across the front edge of the headliner to overhead console opening, then feed about 8” through the small access hole in the headliner above the mirror, leaving about 6" of slack cable for ease of installation / removal.
9. Connect the RJ45 / Ethernet cable into your SGII, reconnect the wire harness connectors for the overhead lights, then carefully feed the wires back into the headliner so that the console will mount up flush to the headliner.
10. Connect ScanGuage II harness to OBDII port and connect RJ45 end to In-Line connector and then connect RJ45 / Ethernet cable to the other side of the In-Line Connector… you’re now on line.
11. Tuck the RJ45 / Ethernet cable into the front edge of the headliner along the top of the windshield, use electricians tape or zip ties to fasten the RJ45 / ethernet cable to the wire loom along A-pillar to keep it from rattling or chaffing and to 'tidy-up' installation.
12. Reinstall the A-pillar cover, put the fuse access panel cover back on, and your done.
Note: I pulled off the sun visor so that I could route my RJ45 / Ethernet cable across the headliner well back of the front edge as I already have signal wires toward the front for my Gentex mirror. I suspect you could also use a wire fish to pull the RJ45 / Ethernet cable across the headliner but I simply prefer to remove the sun visors to free up the headliner so nothing gets buggered-up.
