Finally, a fix for the universally dim parking lights (tail lights, side marker lights, and front parking lights), as well as the dashboard lighting, on Datsun 240Z's, while drastically reducing one of the main causes of system failure by decreasing amperage in the system. This Parking Light Upgrade Harness uses high-quality modern wiring and relays to increase the power available to the lighting, and reduce the amperage that normally flows through the fusebox and combo switch by over 98%! Since the original system did not have a relay, the large amount of extra resistance translates into heat which can melt fuses, overheat wires, and destroy the contacts in the switch. During testing on a side marker light, the voltage to the light before using the kit was approximately 9.5 volts. With the upgrade harness installed, the voltage increased to 11.2 volts, causing a significant brightening of the dash and parking lights. Requires no cutting, drilling, or damage to the existing system. Includes complete instructions.
Only for 240Z's with a 6 pin connector on the headlight switch harness. This Parking Light Upgrade Harness works on all 70-72 240Z's with no restrictions, as well as on 1973 240Z's with a manufacturing date of 2/73 or earlier that ALSO have non-intermittent wipers (with the headlight switch harness that has a 6 pin connector). For 1973 240Z's with production dates of 3/73 or later, OR any 1973 240Z with intermittent wipers (with a headlight switch harness that has a 9 pin connector), see part 12-4653 in Related Items below. Please call with any questions.
