hello , when you got a msd6al you need to put the tach wiring on the box of the msd , but all tach doesnt work with the 6AL

can you tell me what tach model do you use on your beetle ? 

i've got a JAEGER but doesnt work , i know there is 2 model adaptator but prefer to change the tach directly

please help ,  i just finish my engine , and really need a tach to test the engine on the road

I installed a VDO tach with my MSD 6AL and it's worked fine for many years, no issues.

I'd call the Tach manufacturer and see what it would take to make it work -- it would be cheaper than a complete replace,,,,, unless your wanting to update it -- -- go the Summit or Jeg's and look around for something.......

I have an autometer that works fine with my msd

Same here autometer with my msd.

Henk!!!

I know you said you wanted to just change the tach, however if you decide not to, i have an MSD 8910 sat in the garage not being used. It's for sale if you want it.

ok thanks for your answers  , so if i could keep my tach i prefer , but dont know if its the pn8910 or pn8920 tach adapter needeed ?

my tach is an olld Jaeger electronic and i have a pretronix ignitor in my Bosch 010 distributor

i use the white wire on the msd6al

MSD 8920 if you're using magnetic pick up (green and purple wires)

MSD 8910 if you're using the white wire
