Tach pick up wiring

[rickw]

Wiring skyview to io320 with one slick and one lightspeed plasma 2.
From all i have read, the proper way to pick up tach readings is direct off the acs510 key switch L and R posts. It seems that I should use PIN 32 (white/green) for the left slick. Then PIN 35 (green) for the lightspeed. Due to lightspeeds needs, I need to use the LOW VOLTAGE dynon wires right?
Further, then a 30 ohm resistor on each wire just before it clips into the acs510 keytabs, with a bit of good wire to soak up the vibration instead of the resister end being attached directely. Correct?

Anybody with some comments would be welcome. Thanks!

What I do with all theses installations situations is connect the LSE ign (keyswitch option wire) to the Acs switch & then connect the Dynon wires with resistors to L & R ign positions on the switch - hope that's clear

Thanks...BUT.......

I have that much. My issue is the wording in the manual under TACH plead pick ups. There are 4 wires from Dynon. #32,33,34,35. The first two are standard RPM inputs. So..makes sense for the left (MAG) p lead take off. The last line of the instructions says.. "if you have an rpm source that outputs frequency based rpm signals that are smaller than 10 volts about ground-such as LIGHTSPEED ignition outputs-use the low voltage RPM inputs.

SO...is it ok to use PIN 32 standard, for the slick mag, and PIN 35 Low voltage for the right lightspeed EI tach pick up.

Both would come off the acs keyswitch, L for the mag, R for the EI.

THANKS. Happy new year.

I just use pin 33 for the Lse ign in this situation.

Happy New Year to you guys over there - it's 2011 here already ;D

Actually, the hardware is built such that you can mix and match the high and low voltage inputs. So you could send your electronics ignition to the low voltage pin on one side, and your mag to the high voltage pin on the other. The only restriction is that you can only hook up to one "left" and one "right" input.
