Yes! If we get her to RUN. All rest wires are signal sending wires mainly.
Connect the MBSS + common wire to the starter big prong...secondary red battery cable should already be there! Feeding all those breakers(of course battery -)
MBSS ON, all your circuit breakers should be ON, including your DASH!
Ignition SW ON:first position, listen carefull for the fuel pump relay to click then fuel pump kicking ON as well as POWER to the coil!

Did you see my EDIT?
**EDIT** Wait a minute, you have "RED/PUR to RED/PURPLE" however the boat harness has not RED/PUR wire, so do you mean the PUR1 "and" RED wire from the boat spliced into the single RED/PUR of the harness?

To get your engine going temporarily....
BLACK to BLACK ( battery -)
RED/PUR to RED/PUR (battery +)
PUR to PUR (ignition +, this will turn on ignition/fuel pump relays)
YEL/RED to YEL/RED. (starter relay)

I see now where that purple 2 went to...connected to your old stater because it had a mechanical ignition! Anyhow your new starter doesn't need this purple2 wire so we can ignore it.

BLACK(NEW)TO BLACK (CAB): BATTERY -
RED/PURPLE(NEW) TO RED THICK(CAB):BATTERY +
PURPLE (NEW) TO PURPLE1(CAB): IGNITION +;PURPLE1(CAB)SHOULD BE CONNECTED TO IGNITION SW "I" TERMINAL.
YEL/RED (NEW) TO YEL/RED(CAB) : STARTER RELAY(NEW) IGNITION SW "S" TERMINAL(CABIN)

MBSS on, you should be getting power to the ECM!
Also 3 negative(ground) connection points.

Okay, not able to get my Tach working......... I tried the grey to grey, nothing. I feel like it should just be straight forward, but maybe I'm missing something??? Anyone have thoughts on this?

I have a Sun Runner 245 and need a full wiring diagam for it. It seems all articles on this forum no longer work because of Photo Bucket. Any portions of the diagram would be greatly appreciated especially the instrument panel wiring

welcome to the club Gibson! I see you dug out the old thread.
yup all my precious pics are not viewable anymore :angry: ... I'll see what I can dig out.
what are we doing to your Sunrunner? instrument panel wiring is pretty genetic.
