The KA harness runs from the passenger side firewall and onto the engine. Take your time and disconnect all the necessary plugs then move if off and away from the engine. We’ll get back to extracting it from the chassis later on.

Next, disconnect the throttle and cruise control cable.

Using two 10mm wrenches loosen the four bolts on the fan. Then just let it rest inside the shroud.

Remove the top and bottom rad hoses along with the two mounting brackets holding the radiator in place.

Yank the cruise control system out since it won’t work with the SR. Add it to the KA scrap pile.

The power steering lines are pretty simple to disconnect. One big nut and one worm clamp need to be removed.

Heat shrink tubing and a heat-gun is optional, but gives the
modifications a professional touch and is less prone to potential
future problems. The first modification required is replacing the SR
dash connector with the stock KA dash connector. The SR dash connector
(white, as shown in Figure 1) will not mate with the KA dash harness,
so it needs to be replaced with the KA dash connector. Cut both the SR
& KA dash connectors, and wire the KA one to the SR harness using
the table & wiring color guide below.

Hi, so I just picked up a 240sx. I’m familiar with the cars but this will be my fist Sr swap. I’m all for buying the premade harness but if the engine is coming with the engine harness and ecu, is it still necessary to buy the premade harness or is the sr harness just plug and play into the car? Thanks.
