RMA

^^ I dont see why not .. the engine side of the harness should stay untouched .. the part they will modify is the 3 connectors that supply power ,signals to the cluster and ignition .

but i havent seen their harnesses just from what i know on doing mine .

there price is a little steep.. around 500$ i think. honestly if you have a good spot to lay the harness out along with your diagrams you can do it in a few hours or less.. all you are doing is conecting some power wires, few grounds, some key on powers and thats about it.. for the gauges, you run 3 wires, water temp( use the stock lexus sender) oil pressure(use the stock lexus wire just swap the switch for a sending unit) and tach(use stock lexus wire from one of the igniters, 4cylinder tach required)

keep your stock harness from your runner, were it plugs into the body by the ecu simply
cut 6-10 inches from the plug(engine side) leave the body side alone... get your wiring diagrams and find out witch wire does what, tie them into the starter relay, key on 12v, grounds, 3 signals (tach/water/oil)
and you now have full working gauges and a running lexus in your runner... o not to mention the extra 5-600(-10 for the 12pack of cold beer/mt dew) bones you just saved, and now you know your wiring like the back of your hand from stairing at diagrams for an hour... hmm 500 bucks? thats a front and rear lockright!, or a new set of tires! or this and that? anyway you can ask rma and myself its scary at first but once you get going its realy simple use the diagram on rma's first build thread to get the engine runing and then warry about the gauges.

o i forgot that the lextreme diagram is for your own relays, the way i did it used the factory relays/fuses. i did have to wire in a fuel pump relay, it just turns on with key on power. simple.

Wiring is super easy on these things if you can read a schematic and just follow a couple easy tips that are posted all over the Lextreme forum. But if you are intimidated by wiring or just want to plug and play $500 is cheap and will save you all sorts of hassle. Phoenix guy http://www.phoenixtuning.com/ is doing a great service to swappers IMO as he could charge more. I wouldn't take the risk of sending Venom one dollar. I haven't heard anything good from previous customers of theirs.
