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For service purposes, both Part Numbers, DAC-1212 or DRC-2470, will be superceded by the Model 32RA Relay, P/N TKC-5083.
