I thought it might be worthwhile to attempt to clarify which starter relays can be used.
the unit on my bike is bosch part # 0 332 002 161
the link in this thread
http://www.motobrick.com/index.php?topic=3262.msg19736#msg19736 is to bosch unit # 0 332 002 150
I called texas industrial and they checked with a technician who said the 150 would work fine. The difference being an added resistor to the 161 module.
There is also this module being sold as an "exact bmw replacement" here
http://www.euromotoelectrics.com/BOSCH-Starter-Relay-BMW-K-61-31-1-459-008-p/rel-k008.htmIf you look at the diagram imprinted is contains 2 diodes and is identical to the diagram on the bosch unit # 0 332 002 156 (

Not to confuse matters but there are Tyco part numbers which correlate to these bosch units.
V23232 D0001 X001 corresponds to the bosch 150. This tyco unit is noted as workable in the thread listed above, which would jive with what texas industrial told me re: the 150 unit.
V23232 A0001 X003 corresponds to the bosch 156
It appears there are 2 scenarios.
(1) the bosch 0 332 002 150, and tyco V23232 D0001 X001 are viable alternatives to the 161.
(2) if the euromotoelectrics site is correct in listing as OEM a module showing 2 diodes, then along with (1) there is also the option of the bosch 0 332 002 156 and tyco V23232 A0001 X003
Does anyone have 1st hand experience with these other relays? It would be good knowledge to know if there are 4 alternative modules, if only to have a cheap spare.
