Does any one, or would some one be willing to make a ready to rock loom for the conversion ?

yep I will make you one.

Gona cost you a lot for the postage stamp to send it


There is no need to change the wiring just put the loom off your B200 onto it.

That is unless you are talking about doing a turbo swap

Yet another of my past midnight vagueness, yes of course I want das turbine

It's a hell of a lot of work the LH 2.4 wiring. I've done 90% of my loom for the engine with something like 5 wires to splice into the dash / ignition barrel and a few lives. Then the standard 300 engine loom can be removed.

Its basically a matter of stripping all the un-necessary stuff out the 940 loom then taping it all back together.

Off the top of my head the connections to the stock 300 wiring is:
-battery light/ alternator d+ > LH ECU thin red wire
-Ignition live from switch > Fusebox/ LH relay (big white one), ignition stuff, LH ECU
-Fuel pump live > Pink wire from LH relay via a fuse
-Rev counter signal > R-W wire from coil
-Battery > Fuses and radio interference relay

there's meant to be a feed from the back of the donor car speedo which does something with the idle control valve. Its a Violet and white wire from the LH ecu. On 300's we dont have electronic speedos so this can't be connected, dunno what the effect is, think its something to do with idling high for brake vacuum when you are slowing doen.

I'm in the process of making a diagram / how to for the LH wiring but just havn't got round to it. There is this:



which i did a while ago, it doesn't show the connectors which makes it useless when you are pulling a loom from a donor car but could be good for fault finding one the new looms made.

Hope that helps, feel free to ask for anything else and I'll see what I can do. I'd offer to make you a loom but am busy building two at the moment lol

The f7x's need the same, ask Adam about it

There is a sensor that will fit to do the job.

Apparently the deceleration fuel cut doesn't work on the LH2.4 when this is disconnected. Which is odd because the fuel cut is based on rpm as far as I can tell.
