Steph,
Are you sure that the gage is electric? Most after-market gages
were mechanical. Therefore not needing the sending unit. The
three prong sending units were used with the brake sensor to
illuminate that light as well. I have put a tee in to tap off
for my pressure gage.

Subject: Re: oil pressure light
[snip]
My Spit engine... actually my wife's spit engine had been stooped for 5-10
years before I acquired the car. The engine is running fine but the oil
pressure is very low. At least according the the Oil Presure gauge. Changing
the unit would be the easiest way to confirm this.
Here's my question: For a '69 Spit with a Oil Pressure gauge (not light),
which sending unit do I need to get? The 3 prongs version or the 1 prong
version?
I checked on SpitBits site and for the Mark 1 to III, the 1 prong version is
listed. For the Mark IV and 1500, both are listed. I'm no electrical engineer
but I would thing that for a warning light you would need only 1 prong but for
the gauge, you would need the 3 prong version.
I'm asking 'cause my gauges are not original. There should be only 2 gauges in
my Spit but currently I have 5. I know that Fuel is one of the originals but I
don't know which one would the second one would be in the original
configuration.
Thanks
