I am hooking up all the D-Jet components and i have a few questions. My motor is a 2.0 out of a 1975 car built to a 2056 with a Raby FI cam. I'm using all stock FI.
I might have forgotten something. I have my head temp sender but I'm not sure how it connects. Tin is installed so I see that is goes into the hole next to the #3 intake but does it screw into the head somewhere? Do i have to pull the tin off to install it?
Next:
I see on my harness a plug for the air flow meter but my car came with a stupid aftermarket air cleaner. Where shiuld the AFM be? Is it attached to the stock air cleaner like my bus and 944 or is it a separate thing attached next to the battery tray?
One more:
My heads have two breather holes each adjacent to the intakes. I am told I should block these off. Anyone know what thread they are? When I got the car they were blocked with bronze pipe fittings. Should I make one of these a proper breather?
Thanks!
As for the head temp sensor it is attached to the cylinder head between cylinder 3 and 4 but closer to cylinder 3, access is gained through the hole in the engine tin on that side. If you look in there and see a boss but no threaded hole, the heads may have been switched or two left bank heads were used.
D jet does not use an air flow meter. Show the plug and we can tell you what it connects to. The vents in the heads are non threaded 13mm tubes. They should be connected to the anti flash valve that goes into the stock air cleaner. I have 2.0 air cleaners if you want the correct hookups.

D-Jet = no air flow meter. That answers that.
I'll root around more for the temp sending hole. Sounds like I need to pull the tin. Bummer. You guys make a good point about switching the heads. I thought I paid attention to this. I'll have a look.
I'll take a picture of my heads and get more input on the mystery holes.
Thanks!
Hopefully you don't need to swap the heads around..
Are these stock 75 heads? Then those holes are for the EGR plumbing and Air pump. Block em off with valve adjusting screws
Post pictures of the mystery connector and the holes.

These things are on both heads and both sides of the air intake. They were plugged with household pipe fittings.
The hole for that CHT sender is normally found on the passenger side cylinder head.
The access hole in the tin is obscured by the #3 intake runner.
There is supposed to be a grommet in the tin to support the wire and prevent too much cooling air from escaping.
With the intake off you may be able to install the sender without removing the tin.
The arrowed holes are from the air-pump (emission control) fittings to the exhaust ports.
The larger valve adjusters have the correct thread unless a PO re-tapped the holes for a different type fitting.
As long as they're plugged leave 'em alone.
So, heads are bass akwards. What's the penalty for leaving them and pulling head temp off of #1? Any other issues?
