Could you also describe where the temp > sender uner the air filter is. The temp sender is on the RHD bank at the very back under (See parts manual Section 1, Sub 1, group 5 item 45) or http://www.usadmc.com/dmcstore/ViewDir.asp?PageID=10&PageCat=1%2DEngine item 45. $20 from DMCH, have tried cross referencing them but its finding one callibrated to the gauge. But as i said b4 do NOT ground the wire otherwise you will damage the gauge. Cheers Chris S
