指(zhi)示燈線(xian)路(lu)的(de)正確連(lian)接需依據其功能和電路(lu)要(yao)求，且要(yao)做(zuo)好準備、按步驟(zou)規(gui)范操(cao)作并(bing)留意(yi)要(yao)點 。

指(zhi)示燈(deng)(deng)(deng)線(xian)(xian)(xian)路(lu)(lu)連(lian)(lian)(lian)接(jie)(jie)前，要(yao)(yao)(yao)明(ming)確(que)其功能(neng)與電(dian)路(lu)(lu)需(xu)求(qiu)(qiu)(qiu)，同(tong)時準備好(hao)(hao)質(zhi)量完好(hao)(hao)、規格匹配的(de)燈(deng)(deng)(deng)泡(pao)、導(dao)線(xian)(xian)(xian)等部件。先查(cha)看(kan)車(che)輛(liang)(liang)(liang)電(dian)路(lu)(lu)圖明(ming)確(que)連(lian)(lian)(lian)接(jie)(jie)位(wei)置與走向，再進(jin)行線(xian)(xian)(xian)路(lu)(lu)剝(bo)皮和(he)接(jie)(jie)線(xian)(xian)(xian)，剝(bo)皮長度要(yao)(yao)(yao)適宜，用合適工具保證(zheng)連(lian)(lian)(lian)接(jie)(jie)牢固(gu)、接(jie)(jie)觸良好(hao)(hao)。此外，需(xu)按車(che)輛(liang)(liang)(liang)要(yao)(yao)(yao)求(qiu)(qiu)(qiu)正確(que)安(an)裝保險絲(si)和(he)繼電(dian)器。不同(tong)指(zhi)示燈(deng)(deng)(deng)連(lian)(lian)(lian)接(jie)(jie)要(yao)(yao)(yao)點有別，剎(cha)(cha)車(che)指(zhi)示燈(deng)(deng)(deng)要(yao)(yao)(yao)連(lian)(lian)(lian)剎(cha)(cha)車(che)踏板傳感器，保證(zheng)線(xian)(xian)(xian)路(lu)(lu)無(wu)破損(sun)和(he)短(duan)路(lu)(lu)；轉(zhuan)向燈(deng)(deng)(deng)要(yao)(yao)(yao)與轉(zhuan)向開關和(he)閃光繼電(dian)器相連(lian)(lian)(lian)，區分(fen)左右(you)線(xian)(xian)(xian)路(lu)(lu)；故障指(zhi)示燈(deng)(deng)(deng)連(lian)(lian)(lian)接(jie)(jie)車(che)輛(liang)(liang)(liang)各傳感器，做好(hao)(hao)線(xian)(xian)(xian)路(lu)(lu)屏蔽。在連(lian)(lian)(lian)接(jie)(jie)指(zhi)示燈(deng)(deng)(deng)線(xian)(xian)(xian)路(lu)(lu)時，要(yao)(yao)(yao)時刻把安(an)全放在首(shou)位(wei)，確(que)保斷電(dian)操作(zuo)。遵循(xun)接(jie)(jie)線(xian)(xian)(xian)順序，注重接(jie)(jie)線(xian)(xian)(xian)質(zhi)量，防(fang)止短(duan)路(lu)(lu)情況發生(sheng)，對于有極性要(yao)(yao)(yao)求(qiu)(qiu)(qiu)的(de)指(zhi)示燈(deng)(deng)(deng)要(yao)(yao)(yao)特別注意極性，做好(hao)(hao)絕(jue)緣處理。總之，指(zhi)示燈(deng)(deng)(deng)線(xian)(xian)(xian)路(lu)(lu)正確(que)連(lian)(lian)(lian)接(jie)(jie)是車(che)輛(liang)(liang)(liang)正常運行的(de)保障，連(lian)(lian)(lian)接(jie)(jie)過程要(yao)(yao)(yao)嚴謹規范。
