where did you route the o2 harness ? And vacuum line.


I'm halfway done with the install. Got new injectors in place. Flex fuel sensor plumbed in. O2 bung welded in. Hoping to finish up tomorrow and looking for ideas for a clean install.
 
pull the yellow plug from the AC grommet (the one with the vac lines )
de-pin the O2 cable end and it will fit through the hole
you could run the vac but i prefer to leave the map in the engine bay and run the map wires that are already in the car ( at the dashboard harness connector above the ECU ) to the casper adapter MAP plug
seal hole with butyl or a soft sealer
 
the map wiring is still there to mount under the hood as its part of the engine harness and there is only one version of that harness
the digital dash is wired different from the analog and it doesnt support map sensor but the engine harness with the map wires still plugs up to it
on the dash connector the lt green (map signal) and grey (5v) are the first two wires from left to right and at furthest right is the black which is the ground that runs to map sensor connector under the hood , these wires can be cut and connected to the casper adapter map plug
casper also sells a plug and play adapter http://www.casperselectronics.com/cart/index.php?route=product/product&product_id=692&search=xfi connects between the dash harness and engine harness that allows the xfi adapter map plug to connect and then the map wire under hood will have power and ground even with a digital dash and no wiring is needed by the user ,
