Instrument panel wiring

I am rewiring my 79 F150 using a painless wiring harness. Haven't had too many problems till the instrument panel. I have a chiltons and haynes repair books. The wiring diagrams have conflicting color codes.
What I need is, how do I hook up the gauge voltage regulator? Does it need power? Also the ammeter? The painless install manual is vauge on these two points. Any help would be appreciated.

The voltage regulator needs 12v for an input. It puts out a pulsing 5v. I would use a voltmeter in place of the ammeter. It is easier to hook up. Most ammeters hardly move unless you have a massive discharge.

Instrument panel wiring

I have rewired my 78 F250 made my own harnesses here is the dash pannel connection pin layout I have made for myself and everythimg works
Dash Board

1 ------------
2 ------------
3 ------------
4 ------------ Temperature gauge
5 ------------ Oil gauge
6 ------------ Indicator right
7 ------------ Amp meter
8 ------------ Earth
9 ------------ Amp meter
10 ------------ Dash lights
11 ------------ Bright indicator
12 ------------ Indicator left
13 ------------ Fuel gauge
14 ------------ Ignition

As the story of the ammeter I much prefer the ammeter and I got mine to read as low as 5 amps either discharge or charge. If you are interested e-mail me giuseppi@intecom.co.za it is a long proces

How about writing it up (with photos) as a HOW TO Tech article and submit to the webmaster to receive a t-shirt ?

Instrument panel wiring

[updated:LAST EDITED ON 23-Nov-02 AT 01:48 PM (EST)]Just my two cents: There seems to be controversy in some circles over which is best; idiot light, ammeter, or voltage meter. In my experience as a mechanic I have found that the idiot light only indicates a problem after it has occured, including any damage resulting. The ammeter also only indicates a problem, and is sometimes slow to react. Perhaps this fellows article will help a lot with this. But the voltage indicator, my personal favorite, constantly indicates exactly what the charging system is doing at all times, and a good interpretation if the readings can often catch problems before they cause damage. And they are an easy install. I look forward to this fellows article on ammeters.
