New Engine Bay Wire Harnesses

I just pulled my engine out of my 89 'vert this weekend. While unding the harnesses, both the injector hanress and the main harness, I found most of the tabs were broken off. I also noticed that some yahoo that had the car before me spliced the wires a couple of times. Can anyone tell me where I can find new harnesses? I have been searching the internet and found the injector harness for around $300, but I have not found the main engine harness yet.

thanks for the help. Not sure what to do yet. I know that the injector harness will be a direct fit, but the engine harness may be another question. I was reading that ther 89 was a one year only harness due to the fact that it was the only year with MAF and no airbag. I may have to try and repair it.
