Its going well so far ive just finished up wiring gauges and they look pretty nice. I had to modify the pod bezels to fit aftermarket gauges. Much like my fan shroud job, you can't even tell I chopped on it which makes me really. I'm still waiting for a few items to come in so I can finish my ps plumbing. Still need to throw the trans in as well but the big ticket items are finished.
Are you referring to your clutch cable hole?

No, a new hole for the wiring harness, on the 700 series there is no good place to run the ecu/ezk through the firewall, so I need to cut a new hole . My car is a factory hydro clutch, so that is all good
 
So I've got the car to turn over and start but the problem is when i turn the key the starter won't turn. I had to hot wire from the starter ignition terminal to the battery to make it spin. A couple really weird things are at play here. I can get the starter to spin so I assume the starter isn't the issue, but this starter came off a car that had the very same issue before I tore it apart. It isn't fair to assume it's the ignition switch because the ignition switch worked perfectly fine before this project started. I figured I'd throw another starter in it and see what happens first. In the mean time cam someone confirm the battery, starter, and alternator wiring for me? I'm going from battery terminal to B+ alternator terminal, and from the starter straight to the battery terminal. Also I have a electric fan 12v switched wire spliced into the terminal for the starters ignition wire. Anyone see anything wrong with that arrangement?
 
The wire as setup by Volvo is to run a battery cable to the starter. Then from the same terminal on the starter a cable runs to the alternator B+. 12v switched for the fan on the ignition power circuit is not ok. The fan draws a lot of current and would affect ignition operation including the starter if the fan was on. Wire the fan with a relay that is switched by a temp sensor.

Okay I can easily make a wire to go from the starter to the alternator. I'll explain my fan wiring a little more, I've got the fan relay setup from a 940 in there. So it does have a wire for each fan speed that goes to a hose coupler with two different temp sensors in it on the top rad hose. The power cable from that relay goes to a generic 40a relay then from there it's got a fused wire going to the battery and the 12v switched wire going to the ignition wire. Should I choose another source for my 12v switched power like the blower motor fuse?
 
If that is only the trigger wire for the fan relay going to the ignition that will be OK. It's the large current supply wire that you want to go to the battery. I don't think you need the generic relay in the circuit. The fan relay is already handling the power for the fans with a switched power lead and the sensors to turn the speeds on.

I thought that as well but I saw other write ups online that suggested I use one. I believe I need to get the starter figured out first then I can test the fan more.

Here is the diagram I used to wire my fan.

OK I see what you made and that's fine. The extra relay makes it so the fan only runs with the key on.

It might be a few weeks before I can get back on that starter issue. I've got another car occupying the lift at the moment and its going to need a lot of work. Poor project planning on my part.
