Just checking, are the taillight bulbs interchangeable between S4/S5? What about oil injectors?

Yes all are interchangeable, bulbs are bulbs , and the oil injectors too, are a better design (easier to remove).......................................FP

The S5 oil injectors are a million times better designed. You can actually get a deep socket on them rather than trying to jam a wrench under the top.

Everything for the taillights is interchangeable, except on mine, the harness for the bulbs won't sit properly on the inner brake lights. Maybe something is messed up on the harness, or the tails, but I know I had to work at it for a good 10 minutes to get them jammed in there without actually breaking something more.

s4 harness in s5 tails take a bit of working to get right, you can either dremmel it a bit, or what I did was hold it on a angle starting one of the tabs, then rotate it until the other 2 line up

Thanks. Lucy's missing the inboard bulbs on both lamp assemblies. Nothing else, just the bulbs. [?]
As for the oil injectors, After replacing the injection lines/fuel rails the #1 line isn't filling with oil, and as I need to go back to the junkyard to try and find/retrieve a socket set accidentally left under the hood of a '86 FC, thought I could grab the injector in case it was bad.

And while 'm on the subject...
When I was replacing the injectors, I mixed-up the #1 and #2 injectors (didn't realize they were different lengths). I was wondering why the #2 wasn't going into the #1 hole, and noticed what looked like a plug in the bung. It appeared to have a slot for a screwdriver in the top and I thought that it might have unscrewed partially when I removed the injector.
Then I noticed that the injector in the #2 hole wasn't as long as the one in the #4 hole. At that point I stopped trying to unscrew the 'plug, and swapped the injectors back to their respective bungs. What are those 'plugs' and could my monkeying have damaged anything to where it would cause my symptom?
But then again, the aux ports won't open anymore, so maybe I buggered-up a vac line or something.

Yeah we had S5 tails (among other parts) on our S4 car. No duct tape or zip ties needed or nothin'!

To install the s5 lights in a s4 just, file out the backup light hole so the sockets will clear the sheet metal, then install them.................... the screws from under the oil injectors is installed to regulate oil flow they are just little jets ,if oil is not flowing check the manual for amount required and test them,may be the oil metering rod is not working(stuck). regarding the aux ports they work (open) from exaust gas pressure which runs from the CAT,or header
