for the water temp do i put the sensor in the upper or lower rad hose
for the egt gauge can i put i before the cat but were the exhaust manifold pipes go into one
or right after the cat
any help would be apprectated

 

For water temp, take out your stock sender. put the after market one in. cut the wire going to your stock gauge, hook it to your new gauge. The rest I dont know
