Bird Nest Under Dash

[powder60]

I'm sure many of you have had your wiring in your trucks look like a family of birds have made their home under the dash. The mess is so bad that I don't even have a clue where to begin. I'm thinking about taking it to a electrical auto shop and having them straighten the mess out. Has anybody had a shop do this for them and how much can I expect to pay. Not sure if I can afford to do a complete new wiring harness at this time. Maybe a front wiring harness? Any thoughts and recommendations would be great. ....Powder 60
