Hi Michael,

I ordered the DUI M35820BL and new wires from Summit and received it yesterday. I have been reading through the instructions and looking at some old wiring diagrams. What I am finding looking at mine and looking at my neighbors Ski Centurion, their have been changes to his and mine and noticing a lot of differences. I have a few questions and have attached some pictures. One of the things that i have been dealing with is a starting solenoid for years. It goes bad and has to be replaced. my neighbors doesn't have it anymore and is wired to the solenoid on the starter. I have left it as I found it because it works and didnt want to mess with things not knowing exactly what i am doing. Take a look at the pic. Have you come across these on your boats? My plan is to leave it on. Here are my questions

1. Reading the DUI instructions it calls for a 12 gauge wire from the ignition switch to the positive side of the distributor. My question is, can I run this wire from the positive pole of the starting solenoid? I believe this will then allow the distributor to work off of the ignition switch.

2. I have also attached a picture of my coil, which I think maybe wired wrong for the Tach. My Tach hasn't worked in years. I thought It was the Tach itself but thinking maybe it is wired wrong. But my question is....I believe the new DUI has an internal coil so that I don't need the old coil anymore. If that's the case what do I do with the wires that normally connect to the coil? The colors don't seem to match the wiring diagrams and don't know what is original and what may have been changed by the previous owners. I have purple wire running off the positive side of the coil to the distributor. I believe this is the power to the coil but. Not sure where the tach wire is/goes. The white wire on the positive side of the coil I believe ties into the wiring harness. I am 2 hours away from the boat. Anyways, just trying to figure out what to do with the wires on the coil. Need to find the tach wire...but then cap off the others?

I appreciate your help. I am really bad with wiring.

thanks
