currymonster Posted June 16, 2007 Share Posted June 16, 2007 hello. can any body help me wire a 3.9 v8 flap type injection into my hybrid? the wires coming from the main 110 loom are- WHITE/RED TWO BROWNS GREEN/BLUE BROWN/YELLOW BROWN/WHITE BLACK/WHITE wires coming from the engine loom harness are- BROWN WHITE/SLATE WHITE/PURPLE BLACK/YELLOW YELLOW ORANGE/BLACK PURPLE/YELLOW any help would be great. thanks, martin Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted June 16, 2007 Share Posted June 16, 2007 I have no idea what the wires from the 110 do, the colours suggest the following functions: WHITE/RED - Starter solenoid (+12v when cranking) TWO BROWNS - Permanent +12v live The rest I can't be certain off the top of my head. As for the EFI loom you probably want to check the wiring diagram but the Haynes Book Of Lies says: BROWN - +12v permanent feed WHITE/SLATE - fuel pump relay coil, wire to ignition switched live WHITE/PURPLE - From fuel pump relay to fuel pump VIA A FUSE (10A should be plenty) BLACK/YELLOW - EFI warning light on dashboard, you can leave this disconnected YELLOW - From road speed transducer ORANGE/BLACK - To auto box neutral switch (I guess this is the start inhibit?) the wire is grounded by the switch but I dunno if that's "ground it to make it work" or "ground it to stop it working" PURPLE/YELLOW - To heated screen, you can probably leave this disconnected although it would serve as a handy "idle up" input if you have anything engine-driven like a winch or compressor.

streaky Posted June 17, 2007 Share Posted June 17, 2007 I did a cut and paste of this. Some parts may be usefull. Vehicle Wiring Colour Code Table Many British designed vehicles use colour coded cables to assist in identifying the various circuits in use. This is an extract from BS-AU7a 1983 Colour Code for Vehicle Wiring, from the British Standards Institution, 2 Park St., London W1A 2BS. Note that these colour codes may not apply directly to older vehicles. For example, the wipers on vehicles up to 1980 (at least) are not on a separate fuse circuit, so they are not orange, but green. Check the schematic for your vehicle to be certain. MAIN TRACER PURPOSE Black All earth connections Black Brown Tachometer generator to tachometer Black Blue Tachometer generator to tachometer Black Red Electric or electronic speedometer to sensor Black Purple Temperature switch to warning light Black Green Relay to radiator fan motor Black Light green Vacuum brake switch or brake differential pressure valve to warning light and/or buzzer Black White Brake fluid level warning light to switch and handbrake switch, or radio to speakers Black yellow Electric speedometer Black Orange Radiator fan motor to thermal switch Blue Lighting switch (head) to dip switch Blue Brown Headlamp relay to headlamp fuse Blue Red Dip switch to headlamp dip beam fuse Fuse to right-hand dip headlamp Blue Light green Headlamp wiper motor to headlamp wash pump motor Blue White a) Dip switch to headlamp main beam fuse B) Headlamp flasher to main beam fuse c) Dip switch main beam warning light d) Dip switch to long-range driving light switch Blue Yellow Long-range driving light switch to lamp Blue Black Fuse to right-hand main headlamp Blue Pink Fuse to left-hand dip headlamp Blue Slate Headlamp main beam fuse to left-hand headlamp or inboard headlamps when independently fused Blue Orange Fuse to right-hand dip headlamp Brown Main battery lead Brow Blue Control box (compensated voltage control only) to ignition switch and lighting switch (feed) Brown Red Compression ignition starting aid to switch Main battery feed to double pole ignition switch Brown Purple Alternator regulator feed Brown Green Dynamo 'F' to controlboxl 'F' Alternator field 'F' to control box 'F' Brown White Ammeter to control box Ammeter to main alternator terminal Brown Yellow Alternator to 'no charge' warning light Brown Black Alternator battery sensing lead Brown Slate Starter relay contact to starter solenoid Brown Orange Fuel shut-off (diesel stop) Green Accessories fused via ignition switch Green Brown Switch to reverse lamp Green Blue Water temperature gauge to temperature unit Green Red Direction indicator switch to left-hand flasher lamps Green Purple Stop lamp switch to stop lamps, or stop lamp switch to lamp failure unit Green Light green Hazard flasher unit to hazard pilot lamp or lamp failure unit to stop lamp bulbs Green White Direction indicator switch to right hand flasher lamps Green Yellow Heater motor to switch single speed (or to 'slow' on tow- or three-speed motor) Green Black Fuel gauge to fuel tank unit or changeover switch or voltage stabilizer to tank units Green Pink Fuse to flasher unit Green Slate a) Heater motor to switch ('fast' on two or three-speed motor) B) Coolant level unit to warning light Green Orange Low fuel level switch to warning light Light green Instrument voltage stabilizer to instruments Light green Brown Flasher switch to flasher unit Light green Blue a) Flasher switch to left-hand flasher warning light B) Coolant level sensor to control unit c) Test switch to coolan level control unit Light green Red Fuel tank changeover switch to right-hand tank unit or entry and exit door closed switch to door actuator Light green Purple Flasher unit to flasher warning light Light green Green Start inhibitor relay to change speed switch;

FridgeFreezer Posted June 17, 2007 Share Posted June 17, 2007 Many of those are indeed correct for the main wiring harness, but with the engine looms LR threw it away and made their own thing up (or used a different standard - the flapper and hotwire colours are different too). Generally the brown = live, white = ignition switched live and black = ground thing holds up anywhere but after that I'd seek out the wiring diagram. I'm pretty sure it's been posted on this forum.

Coastcard Posted June 17, 2007 Share Posted June 17, 2007 I have just done this and put details of how I did it on my V8 Auto Conversion topic in Members vehicles. I didn't include the 10a fuse in the fuel pump line though. FF is knowledgeable, so probably do as he says!! FF (welcome back and congrats ), is there a fuse in the original pump line, coz I couldn't see one on the LR wiring diagram. Can you explain your wisdom please for the benefit of all. Also the V8 Owners Forum - Electrical section has a Sticky at the top with the EFI wiring diagram and an explanation. It is fairly logical once you get your head round it, but definately worth some time planning the best routing. Good luck. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted June 17, 2007 Share Posted June 17, 2007 The HBOL says it's Fuse 18 in a RR which is 10A, and I didn't realise I would need to explain why putting a fuse in a circuit is a good idea but basically blown fuse is preferable to car on fire Quote Link to comment Share on other sites More sharing options...
Coastcard Posted June 18, 2007 Share Posted June 18, 2007 blown fuse is preferable to car on fire Not the way things are going here at the moment I based mine on the Defender diagram. Maybe less to burn in one of these . As said above wisdom would probably dictate a fuse. Quote Link to comment Share on other sites More sharing options...
