New! DUI Relay Installation Kit

Part# HEI-RelayKit This kit allows you to install a DUI distributor into your FJ25/40/45/55 and have it powered directly off the battery through a fused relay that is triggered by the OEM ignition power wire. This hookup kit guarantees the DUI will receive the full battery voltage.

Note: If you have a 1978 to 1980 FJ40 Please read this! Your truck has a resistor wire built into the harness. It is located inside the harness, and is spliced inbetween the key switch and the Black/Yellow wire that went to the OEM Ignition system. This wire takes the place of a ballast resistor and has a resistance of 1.2 Ohms. Its purpose, just like the ballast resistor it replaced, was to reduce the battery voltage on the Black/Yellow ignition wire to about 9 volts to match the low impeadance coil. This reduced voltage is not good for the DUI. The DUI needs the full +12V in order to work as designed.
