if use carb meter, dont have engine check/injector light.

i think can direct plug in.
my ex-satria 1.3 .. its a 2001 (end) version..
direct plug in .. no need rewired anything..

the downside of using carb meter is u dun have the Check engine light like shawnzz says..

but u can always mix and match ..
last time i bought a 2nd putra meter.. the back cover connector spoilt so i took out the meter and put into the 1.3 satria back covers and u get all the lights u want.

I'm driving 1995 1.3 Wira, I did install the additional RPM Meter few years back. Only 2 cable needed. 1 direct tap from ECU, another 1 is electric for the light (Background).

That's all. 5 minutes work.
