Remote Starter install - perplexed at Becm

[awisnia]

Installed a Parrot bluetooth (awesome) unit in my '97 P38a a few weeks ago..went so smoothly, I moved on to the radio control remote starter installation..

Thanks to the rave disk, I THOUGHT it was going to be a piece of cake.

These units are straightforward..you press a button and the device turns on the ignition and then cranks until it senses the running engine (by voltage or tach input)

The factory wiring diagram shows three wires to the Becm from the ingition switch. They sink the inputs to ground at the various switch positions. (accy, run start) three wires, three inputs at the becm.

However, after carfeully soldering into the harness at the becm, things aren't behaving as expected. If I ground the wire at C258-8 ("run" - I think) OR the wire at C257-6 ("Start" - I think) the engine turns over and starts - leaving the starter engaged and running. (the key was not in the ignition)

I'm lost as to why the application of ground at C258-8 would cause the starter to engage when this appears to be the input to turn on the ignition relay ONLY.

I'm tempted to move around to the outputs of the BECM and trigger the ignition relay and starting relay directly, but I'm concerned that the becm may need to turn on other stuff as well....

I'm really still curious as to why the inputs are not working as expected.

I need to do a bit more testing at various states to see what the ignition switch is really doing - maybe the inputs have to happen in a particular order? Maybe the switch shorts all contacts when "off" and I'm feeding back through it?

Anyone??

Everything I read or hear about anyone installing a remote starter always ends up getting removed or paying lots of money to have it sorted out... major issues can occur with remote starters on Land Rovers.
