I would recalibrate the ecu to compensate. That's what I planned on doing.

Glad you asked that. The ECM provides the vehicle speed. Via a speed wire and through the CAN bus. The axle gear ratio and the transfer case ratio are programmed into the ECM. But, requires the low range switch which that is hosted by the BCM. Another reason why I am bringing the BCM into the mix.

The BCM provides...
backup lights
neutral safety switch
cruise control
low range switch

I am putting together a supplementary harness for the BCM to plug into the OBD2 port. (I just need to quit my day job! )

You can still run the VSS or speedometer cable off the LT230. Or, you can run the speed signal from the ECM. Your choice. The E38 ECM has settings for high range gear ratio and low range gear ratio. When the low range switch is tripped, the ECM modifies the signal. That low range switch comes from the BCM.

The D2 LT230 has no VSS, but has a low range switch.

When checking into my harness options I discovered that Speartech no longer prunes the stock harness and that the only option they offer is purchasing a new custom harness. Another board member suggested that I look into Ken Wolkens at Standalone Solutions for modifying the harness. I just got mine back today and happy to say that it looks great. Ken was very responsive both by phone and email. If you are looking to have your existing harness pruned, you might consider this option.

What exactly has to be done to the harness? Doesn't seem like a whole lot.

And why doesn't Ken want to do anymore for this swap? His page clearly says, he'll do any harness...

I plan on doing it myself anyway, just wondering. lol

He disagreed with the addition of tach wire and speedo wire. He has run into problems with certain OS versions not supporting those signals. Because I/we requested adding those wires, he decided he didn't want the headache. Since he won't be flashing the computers, I am a bit puzzled by the attitude.

Strip off unwanted wiring, add a fuse block, add fuel pump relay, add main relay, extend the wiring into the cab and add an OBD2 connector, throttle pedal connector, and MIL light. For emissions, add the fourth O2 sensor (some harnesses), add vent valve wiring, add tank pressure sensor wiring. Add a tach wire with pull-up resistor, add a speedometer wire and pull-up resistor.

Years ago I dealt with http://www.eficonnection.com/eficonn...0Wildside.aspx for a custom harness for adding an LT1/L98 type GM engine into a rock buggy. They might be worth a call/email....

Interested in the pricing information and estimate of overall expense for this - would appreciate a PM.

Maybe Nic would consider posting the BOM in this thread, would have been helpful for me to have known that up front before starting the conversion, at least you can prime the boss then
