Somebody know Wire Color codes

[BigCountryx]

I've got another thread asking the question about a Purple/White wire and a solid White wire that are running to a plug by my fuse block under my dash. Can someone ID this please?

What year truck ?

I was glancing through my diagrams and see purple and white for TBI ECM to EST wire , and also for 89 an later right side power windows .

I really didn't see purple and white on older trucks diagrams .

Now I saw dark blue and white on cruise control diagrams .
