IS THE PRE-ASSM. 3.57 MS 2 WIRED FOR VR. RUNNING A MSD 6AL /CRANK TRIGGER AND TWO HOLLEY TBI'S

Not by default (at least at our shop), but it can be special ordered that way.

So, do I just need a Jumper wire to run a Vr. or do i need a diode or two. Running a 3.57pre assm, with a relay board , msd 6al and crank trigger. thanks Alan

How did you order this one?

Matt, Ordered a Carb to EFI KIT. 3. 57 board and updated firmware 3.0 hooked up stim and everything works, i.e. temp tps, map.

That one would have been set up so it could run fuel only or a 7/8 pin HEI. If you are running an MSD box and not using the HEI module, you'd need to set the jumpers for VR input and install a switching transistor or BIP373 in the Q16 slot.

Thanks Matt.
