Total loss w/ shifty mod diagram included Please Help

[DrGonzo]

This is my first total loss system. I originally had someone setting it up for me and it fell through. I am a bit overwhelmed by this project. I think i am making it a bigger deal than it is because i have heard of so many people having issues with their systems. I am going to knock out the wiring tonight. This is my first time doing any type of wiring and have no electrical knowledge. There are a few questions still and would greatly appreciate any help.

Questions on bilge
- for a bilge I just want to split the violet wire coming from the brain to the shifty mod and add a fuse right?
-What connection should I use to split it?
-Where can I get the proper fuse and holder?

Solenoid questions
- how are people mounting the oem yamaha starter soliniod? It just has 2 slots in the rubber.
-Am I blind I don't see it being marked as positive and negative?
-The wires that come connected are the ground and the coil wires in the diagram right?

Ground questions
-the grounds from both coils and the starter soliniod and the shifty mod will all run to the starter ground?
The brain is grounded via the battery?

Mounting question
What is the best way to mount the total loss plate on a firewall (rickter edge) without drilling through the firewall?

Capping unused wires
-what is a good method for capping off used wires?

Again thanks so much for any help. I am thinking of making a video of my setup if there is any interest.

Any negatives can be connected to any ground point on the engine or battery, it doesn't matter they all create a circuit back to the battery anyway. I had my msd set up on a piece of clear perspex and i put a common ground point on there to run all the negatives to. What brand total loss are you using? What type starter relay are you using? Also, why complicate the bilge setup into the electrics? Just run its own circuit from the battery

I use the Polaris Solenoid, That you can screw to the plate. Also its only like $15. Mine is setup with a ground point on the plate that runs to the engine as well as the battery ground.

Where did you find the plug for the Polaris relay...? Been looking for a while and haven't found the right one yet...

@SpaceCowboy put mine together.

Thanks for the response. I am using the MSD total loss with the oem yamaha soliniod.

What is the best way to add a common ground?

My thoughts on wiring the bilge into the shift module was when the lanyard is not connected the bilge would be off and less likely to drain my battery. Maybe this is not a valid concern.

I actually taped all connections together on the total loss. I would recommend this for first time total loss users. When I get off work I am going to go do all the connections.

These are the questions I still have

-I am still wondering how to tell the difference between positive and negative on the starter soliniod. It is not marked. I'm assuming the side with the black ground coming out close by is the negative. Is that correct? For mounting I am thinking 2 zip ties through each slot in the rubber boot.

-Another thing I am trying to figure out is what connection to use to split the white ignition wires from the brain to go to both the coils. I was thinking there would be some type of y fitting but I do not see one.

- how are you capping unused wires?

-how do I do a common ground on my TL plate?

-dielectric grease vs not? I have heard both

Thanks so much for any help. I'm really trying to get this done today. I owe everyone beers if I ever run into you.

You can kind of see the ground post in the middle of the plate. All grounds go there, then one ground runs to the engine from the same spot.

View attachment 313511 You can kind of see the ground post in the middle of the plate. All grounds go there, then one ground runs to the engine from the same spot.

Thanks so much that makes perfect sense. What are you using as a grounding post? Then I can put the grounds from the soliniod and coils on there then run to the battery and starter. Is there a limit to how many of the ground runs can go on a post?

On a side note since you are a PHP guy have you ridden a powermouse? I'm really excited to step up from my 701 w/ head and bpipe to the powermouse w/ total loss and tnt pipe.

Any stainless bolt will work. Mine is just threaded bolt with a spacer and a couple nuts.

I haven't rode the mouse, but I have a PHP built BB760 in my wife's ski with pfp and charging system on pump gas and it rips. Blows away all similar size engines from other builders I have rode. I run the 898 in my dvx with tl and pfp on race fuel.

1st picture Can anyone tell me what this fitting is for it was supplied by msd with the total loss.

2ND picture And here is the white ignition wires that needs to go to both orange coil wires. The orange coil wires already have male connections. Do I need to cut them off and put both orange in one side of a butt connection with the white one on the other side?

I made a Y in my harness that goes from the coil's bullet connectors to the module's Deutch connector. Used solder and heat shrink.

I'm not so sure this is a good idea, if you get separated from your ski and the lanyard is pulled, I'd rather have the bilge running while I make my way back

Not sure if this was answered yet, but there isn't a negative on the starter relay/solenoid. It's just a relay that internally connects the two large posts when a 12v current is applied across the small brown and black wires. One post goes to the battery + and the other to the starter +. Small brown wire goes to the start switch and the black one is grounded. When the start button is pressed, it completes a circuit allowing 12v to pass through the solenoid to engage the starter.

I die electric grease everything.

Thanks so much for all the insight and responses. I just need to run a few grounds then it's time for timing. I really need to spend some time learning more about electronics.
