Redtop Sr20det wiring harness into usdm 89 s13

[warallthetime3x]

I know someone had to of posted this thread before but I'm on my sidekick and takes forever and all that ****....

But... My engine is in and mounted.all that, the wiring harnes is in...cept I read have to rewire the ecu plug into the ka plug so it fits the ka dash harness...

I read , and it sounds easy and all...til I looked at it...

I got the steps from frsport.com/heavythrottle.com and yeah these wires are different...

On the sr harness there's a red with white stripe...not on theka harness..

Its weird, I mean on frsport.com says to use 6wires....but there's 13 pins/wires on the sr harness and 16 on the ka....if I only use 6 will some stuff not work?

I need some help, thank you....

Pictures would be appreciated greatly thank you
