Tired of replacing angle drives? SpeedBox can help with that.
Purpose:
-to bypass the failure prone angle drive with an electronic unit that uses GPS derived speed to drive the DeLorean speedometer.
Time neeeded:
-1 to 1.5 hours
Parts needed:
-SpeedBox GPS to mechanical drive speed converter, available from Speedhut
https://www.speedhut.com/ecommerce/product/2585/SPEEDBOX™-GPS-VSS-to-Mechanical-Drive-Speed-Converter
-wire stripper and crimper
-butt connectors
-Phillips head screw driver
-nut driver with 7mm, 10mm, and possibly 8mm sockets (I’ll explain later)
Part 1, prep work
Begin by disconnecting vehicle battery. Unhook both speedo cables from your Lambda counter in the driver footwell. Use a Phillips head screwdriver to remove the Lambda counter from it’s bracket. Unhook the electrical connector.
Remove the door buzzer from it’s socket in the driver’s footwell.
Cut and strip the black wire from the buzzer connector (second to last position).
OPTIONAL: cut and strip the purple wire from the buzzer connector (first position). Do this if you plan on providing the SpeedBox with constant power for faster acquisition of satellites (it draws very little power to do this).

Take the wiring harness that comes with the SpeedBox and attach a butt connector to the black wire.
OPTIONAL: attach a butt connector to the red/black wire. This will provide the GPS unit with constant power and enable faster satellite acquisition. This is not required.
The SpeedBox comes with an in-line fuse that needs to be attached to the red wire. You can do this with the butt connectors that are included in the kit. Make sure to put a butt connector an each end of the fused wire.
OPTIONAL: cut the connector off your Lambda counter. Attach the wire coming from the male part of the connector to the other end of the fused wire. You don’t have to reuse the Lambda connector. You could just cut and and splice the green wire from the Lambda connector on your car’s harness.

Part 2, binnacle work
You will need to partially remove the binnacle. You do not need to disconnect any of the electrical connections on the back of the instrument panel. You only need to remove the binnacle a few inches. Please reference this thread:http://dmctalk.org/showthread.php?5085-How-To-Binnacle-Removal-and-Bulb-Replacement.
NOTE: seat removal is not required, but it will give you more space to work with. Also my car had four 7mm nuts and two 8mm nuts holding the binnacle.
With the binnacle partially removed, find where the speedometer cable attaches to the speedometer. Press on the bottom of the retainer clip that holds the cable and gently pull the cable off. Feed the new speedometer cable up through the dash and attach to the back of the speedometer. Remember to push on the bottom of the retainer clip in order to allow the cable to be fully pushed into place. Make sure the cable is secured with a gentle tug. Feed the GPS antenna through the dash and leave it sitting near the windshield just forward of the binnacle opening. Reinstall binnacle. Route the speedometer cable towards the left side of the drivers footwell. Make sure it does not interfere with the trunk opener.

Part 3, installation
Connect the SpeedBox wiring harness to the SpeedBox. Attach speedometer cable and GPS antenna to SpeedBox. Locate bolt near drivers door switches. Remove the 10mm nut and washer. Mount SpeedBox onto bolt and reinstall 10 mm nut. Try to keep the speedometer cable as horizontal as possible. The second picture shows the SpeedBox prior to aligning the cable and tightening the nut.

Attach the fused red wire/recycled Lambda connector to the Lambda connector in the car. If you chose not to recycle the Lambda connector you can just cut and splice the green wire from the vehicle’s Lambda connector.
Attach the black SpeedBox wire to the black wire from the buzzer connector.
OPTIONAL: Attach the red/black wire from the SpeedBox to the purple wire from the buzzer connector.

Hide all the wires behind the vehicle carpeting. Reconnect vehicle battery. Say goodbye to angle drives :)
