I would like to install a green faced VDO oil temp/pressure guage I have found in my
'67 912. Its graduated in F'/PSI 140-280 degrees and 0-140 psi. I assume its an old 911 part. I'd post a pic if I could, but have camera issues. Does anyone know the details as to which senders to use. I realize I'll need an additional wire. Thanks! Keith khbrooks22@lycos.com or 520-404-2875
