Well I'm assuming it was fried since when I got the new one, it worked fine until I tried bypassing the clutch again.
First thing I did was pair the remote to the new brain, then tach learn, then made sure I was on the tach option as you stated.
I was thinking about giving Viper a call, but I'm guessing they won't talk to me since I'm not an authorized installer.
Oh and thanks monty, hope your alarm install finishes up well.

Try setting it on automatic transmission and check the violet wire with a dmm during the crank sequence. See if it goes to 12 volts. If it does it probably isn't fried.

Ok guys somewhat of an update.

I think I burnt out the violet -200mA starter output wire.

Here's how I wired the relay:

86 & 87 go to the yellow clutch switch wire which has constant 12V

30 to the brown clutch switch wire.

85 to the violet - starter output.

Obviously it didn't work so I tried to start the car with the key. I noticed a funny noise was coming from the main unit. I turned the car off and disconnected the violet wire and the sound went away. I put a DIMM on pin 85 and it had const 12V??

Now I thought I had an understanding of relays here but shouldn't pin 85 never see any voltage unless from the violet wire? I wired my trunk release the same way and it works fine, so I don't understand what's going on here? Just to be safe I cut the external diode that was connecting pint 85 and pin 87 and I was still having the same issue.

You had a diode across pins 85 and 87? it's supposed to be 85 and 86, band towards86! If there is no diode present you will get voltage on 85 as it will feed across the coil!

Sorry I mean between 86 and 85 but the band was facing 86.

The middle wire corresponds to 87a and the one at the bottom is 30. Left is 86 and right is 85.

That was the old picture I've since moved the middle wire to pin 87 which is on the top. I cut the diode but I was still seeing 12V even when it was connected. Also, shouldn't the relay have an internal diode?

Why did you eliminate it?  That relay has no wire on pin 87!

Sorry check the last sentence in my previous post. I edited it with more info.

No the diode is external in this case!

If I take pin 85 and put it to ground, I can hear the relay working. However, when I hook it up to the -200mA starter wire it doesn't work and if I manually start the car I hear the main module making a weird vibrating noise until I disconnect the -200mA starter wire from the relay setup.

I also used another relay I had laying around that shows the picture of a diode on the diagram, so I'm assuming it has a diode and I'm still seeing 12V at pin 85. I'm guessing its normal to see 12V at pin 85 until you take it to ground? It just seems like when I hook up the purple wire its just constantly supplying that wire with 12V which is damaging the unit.

Why not put a one amp diode inline on the purple wire! Band towards the alarm!
