Those that have done a 89-91 grill conversion

I was putting the front of my truck back together this past weekend. I had a single headlight set-up and installed a quad (four) headlight Suburban/Blazer core support, grill and lights.

I ended up using the plug for the fuse block from a truck I had that was a quad headlight set-up and splicing the 89-91 harness onto that. Looking back maybe I could have just used my existing harness plug?
The only issue I had was the 89-91 harness had two dark blue and two light blue wires and my plug only had one of each. So I ran both of the same colors into one butt splice.

When I turned on my lights my side marker lights do not come on. When I turn on my turn signal they still don't come on and I was under the impression that the side markers would blink with the turn signals?

Also, while the low beams are on the outside headlights are on but when I click my high beam switch the inside lights come on bright but the outside headlights do not come on; is this the way a 89-91 works?
