A voltemeter should work by measuring its resistance . If you don't have one the you can use a small 12V battery (not a car battery) to connect it. I don't think it matters which way you connected, You should hear a rather loud 'click' when you apply the voltage. I have done that to some 2.7 injectrors that i din't need and no harm was done by doing that.

I wish you would change that wiring harness. It seems that everytime I see one of your posts, you have 5 more codes in the computer. Soldering 32 wires together in a cut harness is absolutely crazy. The car will never be reliable even if you do get it running right. As much as you have been posting, change the damn harness, if that doesnt fix things take it to a mechanic that can troubleshoot the car properly.
