Thread: msd 8969

with a msd 8969 the unit has a normally open and normally closed connection....
ppl are using the no connection to activate both cams right?

could you wire the no connection to the intake cam then use the nc connection connected to a relay to send the ground when the connection is reached the correct window to the exhaust cam?

seems possible but i wonder if the device can use both leads or does using one deactivate the other?


from the msd 8969 pdf...

OUTPUT WIRES

gray wire
Normally Closed. This wire will remove the ground source at your desired
On rpm, and complete the ground circuit at the set Off rpm.




yellow wire
Normally Opened. This wire will provide a ground source at your desired On
rpm, and remove the ground at the set Off rpm.

Note: The output wires are capable of a switch load of 2.5 amps, continuous. The operating
input voltage of the Switch is 9-18 volts.

Just wired mine today.

MSD:
Red - Switched 12v
Yellow - To VVL solenoids
White - RPM signal from dizzy
Black - Ground
Grey - Not used.

Solenoids:
Two of the same colored wires, wire to yellow MSD wire.
Other two wires go to constant 12V battery.

Yellow wire on the MSD box completes your ground to the noids when the activation is set to what RPM you want. Real easy install.



Chris.

yea but i am wanting to turn the high cams on at different rpm values and i am wanting to use the 8969 to do it. i will find the relay i need and see if this works on the vvl switching. thanks for your input though!!!!!!!
