Crownroyal ignition color wires
 

I need the color of the wires for a Mercruiser 5.0 Alpha one ignition. Please help guys my husband took the switch out months ago because he lost the key and now does not remember how the wires go. 3 prong switch. 1994 model inboard/outboard.

It is presently has a larger red wire connected to B and a yellow with tiny re stripe to S and to the I is either a pink or really light red. This is how my husband hook the switch and he can't remember how the wires went.

Fixed
 

Thanks, My husband thinks I'm so wonderful now that I fixed the boat switch.

Good link, I found the wiring colour coding on the site useful

I have been trying to find a engine wiring diagram for a 500Bull Dog 540 v8 !990 throu 96. The engine that uses the electronic box that looks like an MSD unit. I have been looking all over the net. I am using a brand new old stock wire harness and trying to wire it to a 581cid engine with all MSD ign components. Is there anywhere it can buy a schematic without having to buy the whole service manual. Thanks for any info
