Hi all just wondering if anyone can help. I would like to use an output on my mj to control the clutch on my super charger. I have MJ V4


I currently have it wired using a relay and a switch in the diag below am I correct in thinking I can connect the output wire from one of the four output connections to 86 on the relay without damaging the MJ

I also presume the MJ output gives a constant voltage when its activated by the program?



Thanks all

I run a supercharger and I don't care the TB is on the wrong side.

I will be doing something similar for the fuel pump using my MJ V4. Not tried it yet, but was told it was feasable.

I'm also loosing the clutch from my charger...

The user outputs are negative switching so you would connect the user output to pin 85 on your diagram. You would remove the current earth connection and leave the switch on. Examples can be found here: http://www.autosportlabs.net/MJLJ_V4_vehic...tallation_guide

cool so keep the charger earth but disconnect 85 and connect the MJ output.

Found the spare plug pins so I can give it a shot..

Thanks for the help
