This is using the Radio Shack automotive relay and a MSD Trigger. Process is the same for one or two triggers.
The Solenoids have two wires that are the same color those are the grounds. I spliced them together and attached the end to the engine block for the ground. Then the activation wire goes to the relay as I describe below as the “white wire”.
MSD RPM SWITCH
Yellow to Relay
Black to Ground
Red to Power
White to Distributor. Also labeled as the “Reference” wire in the FSM. On the B14 it is the Blue wire on the long plug.
RADIO SHACK 4 PLUG AUTOMOTIVE RELAY
White Wire to #30 (cam activation wire)
Yellow Wire to #85 (from MSD trigger)
Black Wire to #87 (12V Power)
Red Wire to #86 (Switched Power)
On the relay the Yellow is opposite the Red and the White is opposite the black.
I actually have a Question as well. The MSD instructions suggest a switched power to the RPM switch. As it sits I am not using any switched powers at all. Before with the MSD Ignition I talked to the MSD tech line and the told me how to wire some stuff. I think that they said this would not be an issue but I frankly can’t remember. I took the MSD ignition out when my distributor went dead. I just rewired the entire thing with the MSD Ignition no longer in place and this is what I got. If my battery doesn’t go dead I will know. I did use a multichecker to check for current draw. Not sure if I did it right but I was not able to get any draw with the multichecker so I guess it is ok.
We will make this a link in the sticky latter once we have feedback from you all about the instructions.
also, if your ve came without connectors still hooked onto the solenoids, there are two prongs inside each solenoid clip...it doesnt matter which one you choose for power and which for ground as long as one wire from each solenoid goes to a ground and one goes to a power.

I have my rpm switches powered off a constant 12V and I have yet to have any issues. I'm sure it's not ideal, but it hasn't given me any trouble thus far. If it matters....
Hey, in case anyone was interested in wiring up the VVL triggers for a B13 with the separate distributor coil. Here is how we did it.
From the MSD Switch
White - To the green and yellow tach wire at the coil.
Black - To ground
Red - To a power source, either an ignition wire or just to the battery
Yellow - To the ground pin on a 12V relay
Gray - Not used
The tach wire will read the RPM and at the desired swittch point it will switch the yellow wire to ground. At that point the relay will close the circuit for the soleniods and provide a strong steady current. You may not need a relay, but my buddy recommended it and he installed stereos and alarms for 4 years so i trust his judgement. I can post some pictures if someone wants to host them.
I have the MSD switching the ground. But the relay's are switching the power. I was wondering if anyone would notice.
I figured that's how most people would just do it normally, so there won't be power running to the solenoids all the time. I had a problem with a 5 post relay not allowing me to switch via the ground signal, so I borrowed 2 - 4 post Nissan relays from a friend and they allowed me to do this without any problems. Not sure why the others wouldn't allow it, but for some reason they did...
it is recommended that if the device being driven is pulls more than 2 amps that a relay be used, per the instructions for the summit switches. since we were sure how much amperage they drawy, why not use one.

Actually the MSD can only pull like 1.5 amps or slightly less. I tried it without the relay's and it would not fire the selinoids.
Ok sorry for the questions i have my car running good i have mines setup like this
msd switches ground which is the two neg. wires on cam solenoid .The positive on cams are on the relay.So i have the solenoids are not on till the msd triggers the"ground" .MSD power wire is on relay.My question is to steve .If you say have the two so neg wires of solenoids grounded on the motor what are the msd triggering?It sopose to trigger the neg wires on the solenoids which complete a ground.Thats the way i see it.On the msd it RPM switches the way i comprehend what the instructions is saying it only ground the neg wire when it hit rpm you set it at. or its grounded till the rpm thats set.You could hook it up the way you want.
Foget it i see whats going on..lol you hook up the msd neg to relay when you reach the rpm you want it triggers the relay which activate the cams... OHHHH i see now thankx
Does anyone at all knowwhat colour the RPM input signal wire is on the SR16VE engine, in the distributor coil (Or is this where it is to be found)
This is where i must splice the white wire (Cam activation wire) from the MSD unit into, yes ?
This is my first time actually reading up on this. It seems pretty straight forward. Did anybody ever take any pics of this? I just purchased a VE and I was directed here by Chriscar's "HOW TO" thread.
