MODEL:
XJ6 & VDP
SUBJECT:
32RA FUEL INJECTION RELAY
KEY POINTS:
Provides details of the use of a 32RA relay as a replacement for the 29RA unit fitted to earlier vehicles.
Relay Model 29RA, P/N DAC-1212, or Model 32RA, P/N DRC-2470, is used as the combined main/pump relay in the "L" system electronic fuel
injection.
The main relay switches the supply to the ECU and is internally polarity-protected as a safeguard to the ECU. The pump relay, which is controlled by the
ECU, switches the supply to the fuel pump.
For service purposes, both Part Numbers, DAC-1212 or DRC-2470, will be superceded by the Model 32RA Relay, P/N TKC-5083.
