install armor and winch, disconnected??

i am preparing to install my trail gear rock defense front and rear bumpers
and old man emu heavy front and medium rear dakar on their way
was going to install my front and rear bumpers on my lower mileage 2015 TRD OR
for a few weeks before my coworker and i install the lift

so i POR15 my bumpers and installed my ENGO 10k in the bumper last evening
(connected long black neg to bottom port, along with small solenoid connection, 35 ftlb
for the bolts)

now I was going to install rear bumper starting tonight, but when i get to the front install,
wondering if itd be okay to leave the winch disconnected until after i get the lift and wheels done in the next month or so?

should i wrap plastic bag around positive and negative until i get trim pieces, disconnect switch, etc for a proper install done? i had to connect the negative ahead of time because the connection is on bottom of winch, after you bolt down the winch theres not a lot of room to make the connection, let alone if you wait to install bumper first

solenoid comes wired on these, itll only be the long red and long black to rig up at some point
and i think these newer designed engo tapered solenoid box i might be able to fit this without remote solenoid mount (ill deal with that when time comes installing front, and ill just remove solenoid box and pin it up until
im ready to really wire the winch up) i have lambtek switch to install eventually


also anyone think its a bad idea to run +170 front end and 100lb rear end for a month on stock Offroad suspension?


stoking, got 5 mastercraft courser trail AT (i love mastercraft going back 20 years to my jeep TJ days, made by cooper, and x5 american racing outlaw II polished being delivered tomorrow)

thanks in advance
