Hi
Can someone please show me pictures of how they installed a start relay please. Did you mount the relay inside the engine on the firewall?
Thanks
Meg

I don't have a picture of it but I place mine on the fire wall.

That is where I was thinking:)
I am sure this has been talked about but should I just replace the starter and solenoid? I have a solenoid what does it take to swap just that out? Because I have a new bosch solenoid I can use. I cleaned all the connections and put some dielectric grease to help also. Do I have to splice any wires to install this relay. If I do maybe I should just fix the issue instead of chopping wires. Hmmm

If I had my $%@* scanner set up, I could post the prettiest diagram ever.
I placed my relay on the BobD next to the solenoid underneath, NO SPLICING ALLOWED.

To answer the solenoid replacement question,

There are two screws that hold the solenoid to the starter. There is also the ground strap between them. Once these are removed, the solenoid comes off easily.

When I took mine off, the screws did not want to loosen, and I was afraid I would strip them. I applied some PB Blaster, and a little heat, and they came right out.

Pulling the starter is about 30 minutes the first time (if you don't know what you're doing), then 10 minutes the next time. Pulling the solenoid should only take a few minutes once the starter is out.

I'm in the same boat as you, wondering if a new solenoid will help. I just put my old one back for now. If you put in a new solenoid, let me know how it works.

I don't remember cutting wires but I would need to look back to confirm. I think they are all spade connectors and a matter of doing some switching around taking the load off the long wire that runs all the way to the front of the bus and then back to the starter.
I was not having problems with anything in my system but it just made sense to me to take the amperage load off the key switch.?

That picture helps a lot thanks. I may have a couple more questions when I get the relay before I install it.

Also when I had all the connections to the solenoid off and cleaned ...when I put them back and tightened the nut the solenoid kind of turned very slightly. Is that something to worry about? Is there another bolt that might need to be tightened I just am not sure how they are connected but like DJ said there are two screws that connect them hmmmm. Also where is the ground between them? I should clean that too I guess.

Good Writeup Here:

"Stock" setup works like this, the ignition switch triggers the solenoid directly. All solenoid current must pass through the ignition switch.

Adding the hot start relay works like this, the ignition switch triggers the relay. The current for the solenoid passes through the relay.

No cutting wires for the Wolfsburg West kit. Only a screw hole for the mount and another for the ground wire. The rest was plug and play for me.

Yes. The solenoid grounds through its mounting points! The screws musta been loose!

Drober did NOT mean to write that there was a GROUND strap between the solenoid and the stater motor!! It is a mucho Hot POSITIVE bigass cable 12 volts!! to the starter motor itself!!!

Great coffee here at Panera!!!!

That's what I meant! It looks like a groundstrap, but deep in the crevices of my brain I knew that it carries positive voltage to the starter! :-)
