Hope you didn't burn you voltage regulator or clocks yet.
Haven't got time yet to reply in your thread as been busy at work.
Anyway, did several conversion from stock dash to hi-vis ones. From my experience method with JUST swap pins in socket is easy way asking for serious problems. Why?
Simply because there are at least 3 different variants of stock dash having different signal on pin 5. By putting +12V feed on pin4 you can get away if there is oil level or washer fluid level signal, but is there is battery charge signal (from voltage regulator) then you asking for serious problems.
So, in simple words... it's not a matter of just bridge pins 4 and 5!
Let's start again, then...
1. You need to figure out what icon in stock dash is connected to pin 5. As mentioned there are many variants, so this you need to figure out yourself.
2. Remove backing white bazel from hi-viz dash. It's secured by 4 screws in corners. You will see hi-vis dash luminescent panel.

3. Lift up panel, extra care for connection between clocks and panel itself in a top right corner. It's just a lift up matter, but be gentle.

4. Now, you are ready to do some work on hi-vis clocks conversion.

5. First, cut path leading to pin #5. Best location I did show in picture below. For best result use some sharp craft/stanley knife. Remember you dealing with delicate matter - foil.

6. Well, time to get ready for some soldering. It's a tricky part. Circuit paths are within plastic foil, so extra care is necessary. Begin with some preparation: remove thin plastic film from soldering area with sharp knife (scrub one), use a lot of flux. Also flexible thin wire/cable top quality copper recommended. Cut wires exactly to size, strip max. 3mm of insulation, after soldering secure area with patch of insulation tape.
7. OK, ready for making bridge between paths from pin 4 and 5. In picture showed the best location.

8. Now, time to connect remained icon originally from pin 5. Depends of location connect as picture show.

Because out CVR4 website won't let me use high resolution pictures I've used hosting of photobucket.
Well hope it helps
