Jon, I went out and looked at my 02D X33 and what you think is the oil pressure oil line hole is the speedometer cable clamp mount. From what I see in your long shot there is a dimple in the firewall which is parallel to the bottom windshield wiper motor mounting screw. That is where on my car the oil line grommet is.

camaronut, I think it is that way with the two hole as the clamp is made not to rotate, To keep the cable straight coming out of the 4 speed grommet. Thanks, Bob

This is a picture I took of my firewall. I had several holes to fill but the oil line hole is the original....Joe

Hey Joe, thanks for the picture! Your car is an automatic but you can see from your picture that there is a dimple in the firewall where the clamp would be mounted. Thanks, Bob

Thank You Bob! I now know were the speedometer cable goes.:)  And I am back to no gauges and no Tach.  When I bought this car it was in boxes.  CRG site is great.  Helping me a lot.  Jon

Jon, I'm not the expert, but glad to help.

Still looking for an answer of did U17 use a 1/2 hole under the fuse block like U16 or not?

Thanks, Bob

U17 didn't have a hole under the fuse box. The reason being is the wire for the tach was part of the main harnessing. Only U16 had that...Joe

Hi Joe, Thanks for clearing up my confusion! Sometimes these video are so sure of the facts or only half truths. That's why CRG is the best!
Thanks Again!
