Q:Does this tach have a built in rev limiter in it?
A:No, this part Sunpro Super Tach III, Part No. CP7905 does not have a built in rev limiter in it.
Q:will this work with a Unilite Mallory Distributor and a MSD6 ignition
A:This part Sunpro Super Tach III, Part No. CP7905 is universal and not a direct fit for your vehicle. This is a one size fits most, slight modification may be required. NOTE: If your tachometer fails to operate with the MSD installed you may need an MSD Tach Adapter. Before getting an Adapter, try connecting your tachometer trigger wire to the tach output terminal on the side of the MSD. This output produces a 12 volt, square wave. If the tach still does not operate, you will need a Tach Adapter. You may need MSD Part No. 8910 Tach Adapter: If your tachometer was triggered from the coil negative terminal (voltage trigger) and you are using the White wire to trigger the MSD.
Q:How would i go about hooking this up mainly to a 1985 chevy el camino?5 liter v/8
A:Connect the BLACK wire to the negative (-) battery terminal, or a clean unpainted chassis ground using a ring terminal or other suitable means. Connect the RED wire to any vehicle harness wire which is energized with battery voltage, ONLY when the ignition key is in the ON (RUN) position, not off or accessories. Connect the WHITE wire to the instrument panel lighting circuit that is controlled by the instrument panel dimmer control. Connect the GREEN wire to the negative (-) side of the ignition coil. This terminal may also be referred to as the TACH, TACH TEST, DEC, or ECU terminal.
A:The tach should include instructions telling you exactly how to hook it up properly.
