Greetings All: Was a 240 owner waaaaay back when, and now I'm back, having acquired a 92' 240 wagon that begged me to take her home. Freshening her up and decided to have a go at the instruments. Added Dave Barton's white face package and halogen bulbs to the main cluster, and am thinking of installing a marine-grade white faced voltmeter and electric oil pressure gauge in the blanks to the right of the speedo. The questions that come to mind, and for which I need a little assistance are as follows:

1. Is there an open pigtail in the dash wiring that I can tap into for the 12V keyed-hot that I'll need for both meters. Should I go off the fusebox and just run a separate lead?

2. Since several oil gauge packages have a dual-mode sender (they'll operate the warning light [U]and[/U] the gauge, and they give you choices, does anyone know the answers to the following:

a) At how many psi/bar is the factory low oil pressure warning light triggered?
b) Does anyone know the size and thread pitch needed for the sending unit?

Thanks in advance,
B
