Replaced DIC back into dash, re-connected battery, connected valet switch (temporarily), turned key to on and now had Full Engine Power light up in the DIC.
Put everything back together and took the the car for a test run.
Well We’ll Well. I now have a ZR-1 that goes like a ZR-1 should.
Spins up to 7k rpm easily and pulls hard.
Certainly put a smile on my face.😀😀

Just need to track down where to get these little globe/globe holder units from so l can replace the one l robbed .

That’s fantastic! Funny how it’s sometimes the simple things that confound us the most. Great to see you stuck to it and systematically got to the root of the problem. Good work.

I don't know who imports into AU directly. The last time I bought 'NEW' PC74 bulbs I bought MOPAR L000PC74 and they were less than $3 each. They were used on many MOPAR/JEEP through 2007 or so. A person just needs to just confirm 'grey' socket and fit. L'zero, zero,zero PC74

I believe the OP likely just swapped because of the weekend and to confirm his diagnostics. All of us would likely have done the same given the circumstances. I'd think in the after-market even in the AU or like I mentioned from another '90+ DIC the OP can be helped. Many of us have a used DIC with 7 or 8 of what the OP needs. He's just a long ways off!

A GM 25086809 bulb is a PC74 but has a terrible price these days. Still available but expensive!

Thanks to everyone for your assistance and input. Greatly appreciated.
And yes Dave, they are a grey bodied PC74 as mentioned and yes I did the swap just to test. Unreal to think that just that little globe being out was stopping my secondaries from operating. I haven’t even started to look for the globe over here in Oz. Will do that this week, and if don’t do any good, looks like Batee as previously mentioned has them.

Cheers.

As for the #74 bulb, it can be pulled out of the plastic holder and a new one inserted. I did this during my PV and it worked. Good luck and glad to hear you have a Full Power ZR-1 again.

Tried pulling the bulb out of the grey plastic holder, but it smashed doing so. Assumed it wasn’t possible. Can buy them locally here in town at the local Chrysler/Jeep dealer, part number L000PC74. Complete unit at $2.95 each.
The only downside to this outcome is the fuel gauge will probably drop a bit bit quicker than before. HANG ON, no downside, l don’t care.

Cheers, Russell

That's the way I've always done PC base bulbs. Apparently Joel is using the T-1 3/4 vs the purchase of the GM assembled part. The L000PC74 is currently a black base but I'd think fine. The T-1 3/4 bulb I'd think a more difficult find. Is the L000PC74 in stock @ your local dealer?

Bulb is busted now but who knows - maybe the socket!!

Looks like the dealer is maybe only a 10 minute drive?

Best way to remove these tiny wedges is to attach small pieces of 3M double stick tape on both legs of a tweezers. This allows tweezers to grab the bulb with out excessive pressure.

Joel when you have a moment explain to me how to get to these bulbs and where to purchase the #74 bulbs. I have not had the car out since I put the A Molds and new tires on I didn't install the sensors so the low tire pressure light may stay on. Call me I also need your address so I can send you the oil filter. The stickers came in today.

Chrysler / Jeep dealer only 5 minutes from home. Didn’t have them in stock, but the part number came up as correct for the part. 24 hr to order in.
