Wiring LPG on a Flapper EFI system

(1/1)

Greybeard:
Please can someone tell me which wires i need to cut into on a 1989 3.5 efi with flapper injection system. The Haynes manual is wrong and i have checked 3 of them , the wires are located in the drivers footwell. On my 3.9 with hot wire they are the correct yellow colour, on this 3.5 the wires are a completelu different colour.


HELP !!!!!!!!!!   :(  :(  :(  :(

Sorry it doesnt explain very well does it, the wires i need are the injector cut wires.   :oops:  :oops:  :oops:  :oops:  :oops:  :oops:

Range Rover Blues:
Is this sothat the LPG can cut the injectors off? if so my system is installed next to the injector relay (again on a hot-wire).

Have you tried following the pin-out from the ECU?

Greybeard:
It is the injector cut out yes. This is where i have the problem as i do not have a wiring diagram showing the correct info. It is on a Flapper system not hotwire.

jjsaul:
we tried to do this on my RRC (1986 flapper)

gave up in the end and took it to a specialist  :roll:

Snake110:
AFIK you can cut the brown wire with orange tracer off the main
relay under youre seat to isolate the injectors
pop a relay in there so on switching the relay
you cut off the injectors but use the same
feed to open the gas solenoyds
this allows the ecu/fuel pump to remain active
thus keeping a supply of fuel circulating
round the injectors thus keeping em cool.
