Can I use 98 controls and wiring harness with a 1990 motor

[BassPhantom]

I am removing a 1998 Johnson 175 Ficht and installing a 1990 Johnson GT 150 can I use the existing controls and wiring harness. If yes what is needed? Currently have hydro steering can that be using on the GT 150?

Steering and control box and cables yes but the connectors are different on the cable ends at the motor. You will also loose your system check gauge or LED's on the tach. Best bet is to get a new wiring harness and trim harness and start fresh on the wiring.

Is there an adapter for the controls cables (shifter & throttle). In your opinion I would be better off getting and trying to install the wiring harness for the 1990 motor. The boat is a 1998 Triton TR19.

Controll cable are fine. It is electrical cables that need to be swapped.

So what you are telling me is get the old harness and wire it to new controls. How do I handle the warm up level control on the newer controls? What about the tach. Is the key switch anything special?
May just have to splice into some wires???

Thanks for the help.

Throttle cable is throttle cable no effect. Match ignition switch wire for wire. If you have a plug leading to an analog tach (purple, gray, black) that connects to the control box you are fine. The motors prior to 1996 used a big red plug to make the connection. After 1996 they changed to a multi strand system with Deutsch connectors. Splicing is a nightmare.

Thanks...I really don't want to use the external mount controls on the boat if possible. External mount controls are bulky and not pleasing to look at. What about the warm up level on the external mount controls.


So just match up wire for wire on each control.

Same thing there aren't two separate cables that control the throttle. All you need to do is depress the center button on your throttle (lockout) and advance the throttle or if it has the older style chrome throttle pull the lever towards you and advance it. Only wires you should be worried about are on the ignition and trim.

Thanks...Should be able to get over that hurdle...
