I have 92 accord with F18B Swapped in it. I was adjursting the TPS when my friend said you do not need to set the tps even you need to dis connect it because you have old tranny hooked up with F18B. The logic of his comment was that
1. There is a kickdown cable there
2. Have some left over grips as shown in Image



should i change the Tranny if its not the one that came with F18B? would it make difference?

 

the f18b is a really really uncommon motor that's why you're not getting much help

the kickdown cable resides on the opposite side of the tps...though they both sit close together, they both serve different functions altogether

 

TPS and tranny kickdown are not related.
Being the 'B' series I take it this is a PGM EFI model and not the throttle body injection model with the huge air cleaner lid 'A' model?
Did you swap out the TBI 'A' for the B? Did you use the donor cars harness?

If so TPS is the only way the ECU knows what you are doing with the throttle. It needs to be adjusted and connected properly for the ECU to know what is going on. Speed Density cars do not have the advantage of a MAF sensor.

If there is a throttle valve cable, is your car an automatic? If so the adjustment on that cable is that there is no tension on it nor is there any slack. The lever on the transmission should start to move as the throttle opens.
You will have to find where those grips(connectors) go to.

If the car was originally a 1.8 litre I would leave the transmission. If it is an AT, there should be a sticker on the case facing the radiator. It will be ~ 1" x 2" long with a bar code and a four letter code above it 'BOYA' 'AOXA' 'MPJA' etc

Can you take a wider angle of the engine bay?
Most of the connectors on USDM cars are either grey or green, I cannot recall any brown connectors.
