[txcoyote]

Where can I get soime good info on the Hotwire Injection system. I just purchased a complete setup for my 3.5 motor and want to get it installed but I am pretty clueless as to how it works.

Range Rover or Disco Haynes manual, makes sure its the later one with the 3.9 hotwire engines in
Good Luck, but dont forget the hotwire system will make you car sound alot more tame on the over-run !! is that a good thing ??

There's wiring diagrams here www.pistonheads.com/gassing/topic.asp?h=0&f=&t=243015

Essentially you need a power supply to pin 86 of the two tin relays (21 & 22 on the wiring diagram) and to pins 15 and 19 of the ECU, note the wiring diagram shows permanent feeds to relay 22 and pin 15, switched to relay 21 and pin 19.

After that theres a few earths that neatly cluster together and are mounted to the back of the engine on a stud just behind the exhaust manifold on cylinder 7.

ETA: Just been remembed by the post below there's also a copy of the Workshop Manual Diagnostics as jpeg images here www.rangie.com/articles_topic.php?id=167&cat=7&subCat=51

Or a full description, diagnostics etc etc in PDF here www.landrover.ee/est/files/manuals/cars/rrc/rrm_fuel_injection.pdf

Agree as above - Haynes manual - RRover 1970 - 1992 gives full datail / wiring dia. and checking / setting data.
